Machine Language Source code for various programs, mostly cartridges are available here. Some of the material is scanned, but a good portion of it has been retyped and is ready to be assembled. Also, some of it has been dis- assembled and commented. If you're a machine language programmer, then there is a WEALTH of material here:
| 280 Zzzap, Dodgem (Disassembly) | 280 Zzzap / Dodgem Partial (Incomplete) Disassembly. Bally Mfg. Corp. Programmed by Jay Fenton. 1978. A preliminary Z80 disassembly of the 280 Zzzap / Dodgem cartridge. This is the first release of this code. It is very rough: some of the code has been disassembled and the car graphic pattern has been found. Most code is still not commented. |

1) 300 to 2000 BAUD Loader, (Scanned, PDF) 2) 300 to 2000 BAUD Loader, (Ready to Assemble) | 300 to 2000 BAUD Loader (aka 300 Baud to 2000 Baud Tape Conversion Program) By Jay Fenton. 1981. This is the Z80 machine language source code for the 300 Baud to 2000 Baud Tape Conversion Program that is included on pages 104-107 of the "AstroBASIC" manual. This program loads 300-Baud audio tapes generated by the old version of Bally BASIC into the New and Improved version of "AstroBASIC," which utilizes 2000-baud recordings. Once a 300-baud program is loaded into "AstroBASIC," it can be saved in 2000-baud format. This utility is meant to be loaded into "AstroBASIC" using the :RUN command (it will not run as a cartridge). A ready-to-run version of this program is available:

| Amazing Maze / Tic-Tac-Toe | Amazing Maze / Tic-Tac-Toe This cartridge by Bally has been disassembled by Richard Degler. How many times have you introduced someone to Amazing Maze on your Bally machine, only to hear "What's all that it's doing at the bottom?" before every game. When you say "It's still thinking." they ask "About what??" Well, now you can show them with a copy of this X-RAY Mazing Maze binary. This modified version of Amazing Maze shows what the computer is thinking about instead of just the scratchpad area where it is working out the mazes. Now that you can see the maze being generated I've counted several times how many generations of a route it takes for the computer to get one that works. On the "Hard" level I've counted as high as 68 failed routes and as low as four. I did this about six times and the average seemed to be about fifty or so. So perhaps that generation of a good route after four times was a fluke. Give this program a try-- it's pretty neat to know what is going on behind-the-scenes of the maze while it is being created. Also modified slightly is the Tic-Tac-Toe game using circles (there's now actually two different shapes) instead of re-using the square selector... As you can see from the game logic AI, it knows it needs to block or win when there are two of a kind in a row, but besides that it's just random. |

"Arcadian RDOS 1.0" By Stu Haigh 1980. This is a CP/M compatible resident Disk Operating System. This code is designed to interface into the Cromemco software system and is provided with an autoload feature that will load track zero, sector zero of Drive A starting at RAM location 0080. Control will then be passed to the just loaded code at location 0080. The code uses a 5501 as a COM. controller and a 1771 Flex Disk controller. It will support four 5 1/4", or two 5 1/4" and one 9", or two 9" disk drives. The short letter that Stu wrote to Bob Fabris is available here: Here are the photocopied datasheets that were included with Stu's RDOS source code. |

It includes the source for the 4K of System ROM, and the other 4K contain Checkmate, Calculator, Gun Fight and Scribble. The scans of the manual are not needed anymore now that the source-code has been retyped. It is for archival and reference purposes. The "archive" version of the source code assembles to the 8K Bally On-board ROM. It matches EXACTLY with the 3159 version. This version matches VERY closely with the scanned "Nutting Manual" source code, so it is being kept for reference. The "gold standard" version, created and updated by Richard Degler, is the updated assembly source code for ALL THREE versions of the Bally System BIOS. It can be used to recreate any version of the on-board ROMs. By changing the EQUate 0,1s in the first block marked with "###"'s you can conditionally generate either the WHITE.bin or ASTRO.bin (a.k.a BIOS3159.BIN) both known as "OVER" ROMs, in addition to version 0 BALLY.bin (BIOS3164.BIN or "GAME OVER") from the same source code. To understand the differences between these various versions of the On-Board ROMs, there are two different documents to read: 1) Astrocade BIOS Changes Between the On-Board ROMs By Richard Degler - (January 10, 2010) This article covers what was changed between the three Bally / Astrocade System ROMS. This complements the "Astrocade BIOS Comparision FAQ, below. 2)Astrocade BIOS Comparision FAQ By Adam Trionfo - (July 30, 2006) This is a comparison of the first two Astrocade BIOS that were dumped. These two ROM BIOS have nicknames: 3159 ROM and White ROM. There are forty-one bytes that are different between the two. They are listed here with brief comments followed by excerpts from the 3159 ROM Listing to give greater detail. |

Balcheck 1.0, (Ready to Assemble) Balcheck 1.1, (With Comments) | Balcheck This source code is for use with the BalCheck hardware. There is conditional assembly so that it will assemble for the 3159 or the 3164 ROM. Two versions are available. The regular one, plus one that has a thouroughly commented memory test section by David Turner. |

BalCheckHR. Z80 Assembly Language Source Code. By MCM Design (Michael Matte). 2019. This is about 180 pages of handwritten, Z80 assembly language software for the BalCheckHR unit. This hardware allows experienced electronics users to diagnose many problems with a Bally Arcade/Astrocade game console. This device has many improvements over the original BalCheckHR hardware, including special routines to test Astrocade units that have been modified to use high-res mode. This BalCheck software, if you were to type it in, would assemble to an 8K ROM image. On the BalCheckHR hardware, this is bank 0 of the 32K ROM. Here are links to other BalCheckHR documents:

| Bally BASIC Demo Cartridge | Bally BASIC Demo Cartridge Disassembled by Richard Degler in March of 2010. This archive contains the assembly source code for the BASIC Demo cart, information regarding the changes made to the BASIC in the cart, a listing of the BASIC program in the Demo cart and an explanation of Ken Lill's experiments getting the BASIC program to run in Blue Ram BASIC. |

Bally Demo Cartridge, (Ready to Assemble) Bally Demo Cartridge, (PDF) | Bally Demo Cartridge This cartridge demos the capabilities of the Bally / Astrocade. This is also known, sometimes, as the Dealer Demo. |
| Bally Pin, (Ready to Assemble) | Bally Pin aka Astrocade Pinball Partial (Incomplete) Disassembly. Bally Mfg. Corp. Programmed by Bob Ogdon. Audio by Scot Norris. 1979. The idea to hack the tables in Bally Pin led to this disassembly of the game. Only about 2 1/2 hours were spent on version .01 of this disassembly. It's really just an example of how quickly progress can be made using some of the tools available on BallyAlley.com. The current version has much more of the game disassembled. There are very few comments, but they'll be added as time permits. |

BASIC, AstroBASIC Although this Decemeber 1980 assembly listing is labeled as "Bally BASIC," this source code listing actually matches byte-for-byte with the released version of AstroBASIC. AstroBASIC is the version of BASIC that has the tape input/output port included in the cartridge. There are various versions of this listing available. They are:
|
|
Bally BASIC, (Scanned, PDF) Bally BASIC, (Ready to Assemble) | BASIC, Bally BASIC The PDF version was supplied by Brett Bilbrey. The version that can be assembled was created from scratch by Richard Degler using the AstroBASIC source-code as a model. He added additional comments where he could. |
| Blast Droids (Ready to Assemble) | Blast Droids By Esoterica. Written by Dan Drescher, and J.P. Curran. Blast Droids is a 4K cartridge released in 1983. This disassembly was started November 30, 2016 by Adam Trionfo. Most of the game's graphics have been found, but much of the code has not been disassembled. |
| Blue Ram Keyboard Driver Disassembly |
Blue Ram Keyboard Driver Disassembly Richard Degler extracted the BALLY Basic keyboard driver for using the Blue Ram Keybaord from here. This disassembly is quite extensive and, like all of Richard's disassembly work, is very well commented. Included in this archive are: KEYBOARD.PRG (the tape contents - not really a program but direct commands), KEYBOARD.TXT (the raw Basic listing with a data block in the middle), and KEYBOARD.ASM (the disassembly of the driver itself). Most of the machine code was the same as in Blue Ram Basic 1.1 so I already had that commented. Also included the Basic text listing (commented) and a Key Map. |
| Color BASIC, (Ready to Assemble) | BASIC, Color BASIC This version of BASIC was never released for the Astrocade-- it exists as an archived prototype only. This version of the source code was created from scratch by Richard Degler using the AstroBASIC source-code as a model. He added additional comments where he could. |

Chicken! The Bit Fiddlers, 1982. Disassembly, Richard Degler, August 2013. It's late... you've got to get your brood home in time to watch "Fowl Play." The only problem... there's six lanes of freeway between you and home. And every day it seems to get worse... CHICKEN! is a one or two player game of skill. It pits each player against six lanes of highway of ever increasing traffic density. The object, of course, is to get your chickens across the road. This is Richard Degler's disassembly of the Bit Fiddler's "Chicken (The Bit Fiddlers).bin." This game originally loaded via Bally BASIC, AstroBASIC or the "Machine Language Manager." This version of the binary will run as a cartridge. |
| Cosmic Raiders (Disassembly) | Cosmic Raiders Disassembly. Started by Adam Trionfo. Completed by Richard Degler. December 25, 2018. A Z80 disassembly of the Cosmic Raiders cartridge. This is the third release of this code. It is now commented and most everything has been disassembled. Richard comments: Here's "COSMIC RAIDERS 2019.zip" (early VideoCADE #2019 New Year's present) anyway. [...] Check the names of the different fighter patterns - Type-2 and Type-4 might be switched. And notice that the BOMB-Explosion is NOT used for the Bomb! [...] Contains the infamous "LD A,$F0 / OUT ($CC),A" (BASIC equivalant "&(204)=240") which fooled [some few] into believing there was a MYSTIC register hidden in their machine's hardware. Probably just a command to turn off a Printer, UART or Electronic Module in the test bed instead. |
| Crazy Climber (Original Source Code) | Crazy Climber Programmed by Michael Garber. Riff Raff Games. Released in 2011 This is the complete source code for the homebrew version of Crazy Climber, released by Riff Raff Games in 2011. This game was programmed by Michael Garber. Michael allowed the release of this source code on June 11, 2016. Thanks, Michael! |

Dogpatch (2008, Complete Disassembly) Dogpatch (2003, Incomplete Disassembly) | Dog Patch A complete disassembly of the Astrocade cartridge Dogpatch. Originally worked on by Adam Trionfo in 2003 and left in an incomplete state. In 2008 Richard Degler took the source-code and finished the disassembly. Both versions have been left online for comparison purposes. |

1) Fawn Dungeon, (Scanned PDF) 2) Fawn Dungeon, (Ready to Assemble) | Fawn Dungeon This is an incomplete machine language game written by Barry McCleave. The player in this D&D-type game can wander around a maze, but there are no monsters. This is an interesting piece of what might have become something interesting. As it stands, it is little more than a programming exercise. The scanned pdf is an early version of the source code (August 10, 1981) for the Astrocade prototype "Fawn Dungeon." It has some handwritten notes. This 16-page version of the program does not work (the cowboy does not come onto the screen). Using this source-code and the final version of the working prototype, a completed sourcecode was created that assembles EXACTLY as the finished binary version. Barry was in communication with Bob Fabris (the Arcadian newsletter editor) while he was creating and revising his code. Bob had at least two revisions of "Fawn Dungeon" written code, as well as two EPROMs with different versions of the binary on it. Included below are some letters and EARLY code that Barry sent to Bob. Here, Barry is toying with the idea of writing a "Dungeon's and Dragons" game and he thanks Bob for sending him much-needed information on how to program the Bally Arcade in machine language. Letter from Barry McCleave to Bob Fabris (Letter 01) - PDF Version Letter from Barry McCleave to Bob Fabris (Letter 01) - Text Version Letter from Barry McCleave to Bob Fabris (Letter 02) - PDF Version Letter from Barry McCleave to Bob Fabris (Letter 02) - Text Version Here is the first round of coarse code (which here is considered an alpha version). This was included with Barry's second letter. This code is extremely early, crude and handwritten. Bob's copy was a photocopy from Barry and this scan of it is barely legible. Fawn Dungeon (Alpa Code) In his Barry's second letter, he alludes to how to modify a board for an EPROM. He included this hardware and directions for Bob: Modification for 2716 EPROM It is clear that Bob didn't understand everything that Barry was talking about, and so he wrote a letter to someone named "Al" and some or all of what Barry had sent to him to this presumable Bally Arcade guru: Letter from Bob to Al Finally, a schematic was found along with all this paperwork, but it isn't clear if this was originally included with everything: Schematics (not sure if these are related to Fawn Dungeon) |
| The Gate Escape (Z80 Subroutine Disassembly) | The Gate Escape Z80 Subroutine Disassembly. WaveMakers (Mike Peace). Tape 18 (May 1983) "The Gate Escape" is an "AstroBASIC" game that uses CALLs to a short Z80 machine language subroutine called STRDIS (String Display) in the on-board ROM. The subroutine and data is stored in screen RAM from $4EE8 - $4F85. The routine displays the seven different graphics used in the game. This disassembly was created by Adam Trionfo in February 2019. |

1) Goldfish Demo (Scanned) 2) Goldfish Demo (Version 1.01) Ready to assemble. Will NOT run as a cartridge. 3) Goldfish Demo (Versions 1.1-1.4) Zipped archive of three assembly files and one binary file. These WILL run as a cartridge. | Goldfish Demo Goldfish Demo 1.0 is for the Bally Astrocade game console and the Machine Language Manager cartridge. It won't run unless it is loaded from tape into Machine Language Manager. The program is meant to reside at memory location $4B40. In January 2008, Lance F. Squire converted the Goldfish Demo to run as a cartridge. The binary for version 1.1 and the source-code for versions 1.2-1.4 are included in one archive. Version 1.4 is the finished product; it runs perfectly. |

Gorf Arcade Disassembly Game written in TERSE by Jay Fenton, 1981. Machine Language Disassembly by David Turner, January 2020. Gorf, is a fixed space shooter arcade game with five different screens. Jay Fenton designed and programmed Gorf for DNA (Dave Nutting Associates). It was published by Midway in 1981. Like Wizard of War, The Adventures of Robby Roto! (and others), Gorf uses what has been dubbed the "astrocade chipset". In 2018, Jamie Fenton (formally Jay Fenton) donated documentation and hardware items to the Computer History Museum in Mountain View, CA. This included Gorf source code and other documentation related to the game. Gorf was not written in machine language, it was written in a Forth-like language called TERSE (Terse Efficient Recursive Stack Engine) that was developed at DNA. After the TERSE source code for Gorf became available, David Turner, an avid fan of the game, began to use the game's source code to disassemble Gorf and comment it. Details of his work, as well as his in-progress Z80 disassembly for Gorf is in this archive. In Dave's notes, he refers to TERSE and Gorf related documents which are available at the BitSavers archive, here: A video review of Gorf is available here: |

Gunfight: A Z80 Instruction by Instruction Breakdown Michael Matte, 198x. In the 1980s, Michael Matte, a passionate Astrocade user, used the Z80 source code listing for the 8K ROM, available in the "Nutting Manual," as a basis for his detailed breakdown of Gunfight. Michael created the breakdown "to provide beginner assembly or machine language programmers an inside look at the game Gunfight. The documentation will reveal how on-board subroutines in the System ROM can be used to execute particular tasks. The 'special routines' listing can be used as a reference source for programming demos or games." The archive includes Michael Matte's complete, 42-page breakdown of the Astrocade game Gunfight. This breakdown will be most useful if used with the source code for the Bally's 8K system ROM, which is available in the "Nutting Manual." |
| ICBM Attack | ICBM Attack 1982 Disassembly, Version .03 (July 29, 2013) "ICBM Attack" was released in 1982 by Spectre Systems. It was designed and programmed by Brett Bilbrey. The sound is by Marion Nelepa. "ICBM Attack" requires a special analog hand controller to play - it can not be played without it. |
| Incredible Wizard, The | Incredible Wizard, The 1982 Disassembly, Version .05 (April 22, 2016) This is a disassembly of the Wizard of Wor clone for the Astrocade called The Incredible Wizard. This disassembly was begun in November 2011 and has been worked on in fits and starts over the last few years. There is plenty of work that needs to be done, but this is a healthy beginning. The last versions of The Incredible Wizard disassembly are available for reference or comparison purposes:

| Light Pen Sampler | Light Pen Sampler Light pen machine code extracted from "Light Pen Sampler" basic tape maybe written by Craig J Anderson for H.A.R.D.. Reverse-engineered by Richard C Degler on March 3, 2010. |
| Machine Music Demo | Machine Music Demo By Brett Bilbrey Source: Hand-written Bally BASIC Listing The Machine language portion of the code was disassembled by Richard C Degler on October 16, 2011. The zipped archive contains the following programs:
|
|
1) Machine Language Manager, (Scanned PDF) 2) Machine Language Manager, (Ready to Assemble) | Machine Language Manager This is the source code the for Bally / Astrocade cartridge. It is available in both scanned format and a ready to assemble document. |
| Ms. Candyman | Ms. Candyman Disassembly (Partially Commented). L&M Software. Programmed by Andy Guevara. 1983. Ms. Candyman is a 4K cartridge released by L&M Software in 1983 for the Bally Arcade. It was programmed by Andy Guevara. Ms. Candyman is the sequel to Candy Man, which was released on tape. Adam Trionfo began this disassembly when Ms. Candyman was played for the Astrocade High Score Club in June 2017. The HSC thread on AtariAge has plenty of background and information about Ms. Candyman: |

1) Muncher, (Disassembly, Text-- Ready to Assemble) 2) Muncher, (Scanned PDF)(Grayscale) 3) Muncher, (Scanned PDF)(B&W) 4) Muncher (Pac-Man) 8K Hex Listing | Muncher (Pac-Man) This is a disassembly of the "Muncher" cartridge that was done in the early 1980's. This seems to be the disassembly of Astrocade's "Pacman." The word "PAC-MAN" used for the system's on-board menu has been scratched out with pen and rewritten as "MUNCHER." I'm not sure if there are any differences in the rest of the code-- it is possible. The disassembly is 98-pages long with sparse comments. Since the scan is grayscale, the filesize is 43.5MB-- this is a large file. There is a smaller B&W version that is a about 5MB. For a quick look at the disassembly, or to print it, the B&W version is probably the better choice. Also included here, in a separate archive, is the 8K hex listing for "Muncher (Pac-Man)." |

Palo Alto Tiny BASIC, Version 3 By Li-Chen Wang. Article excerpted from PCC's Reference Book of Personal And Home Computing, Edited by Dwight McCabe. 1977. Pages 58-88. Bally BASIC (and "AstroBASIC") are a superset of the original Palo Alto Tiny BASIC. This version of Li-Chen Wang's Palo Alto Tiny BASIC will run on either the 8080 or Z-80, and only uses 2K of core memory. It contains a number of nice features including command abbreviations and error messages. At the end of the listing is a cross reference table for symbols used in the program and also the object code for the program. For further information on Tiny BASIC languages, see Dr. Dobb's Journal, Volume 1.

| RAM Test, (Scanned PDF) | RAM Test (Generic Z-80 Source Code) A five-page scan from Z80 Assembly Language Subroutines by Lance A. Leventhal and Winthrop Saville. This is a generic Z80 routine to perform a RAM test. |
| Seawolf/Missile (Disassembly) | Seawolf/Missile This is a disassembly of the Bally / Astrocade cartridge "Seawolf/Missile" (Videocade #2002). This game was programmed by Rick Spiece and released in 1977. This partial disassembly was started by Adam Trionfo in 2011. The binary output matches byte-for-byte with original cartridge release. Although only one day was spent working with this file, a respectable amount of work was done and it seems worth sharing. |
| Songs, (Ready to Assemble) | Songs This Bally / Astrocade cartridge has been attributed to Scot Norris. This cartridge has been disassembled by Richard Degler. Two versions are included in the zip archive: 1) SONGS.ASM - Version 1.2 - Note Values changed to names found in "Music.lib" 2) SONGS.z80 - Version 1.1 - Note Values only The source code is about 35 pages. |
| Space Fortress (Ready to Assemble) | Space Fortress This Bally / Astrocade cartridge was programmed by Bob Odgon. This cartridge has been disassembled by Adam Trionfo. Currently most of the graphics have been found and much of the program has been disassembled, but only a small portion of it has been commented. |
| Space Invaders (Prototype) | Space Invaders (Prototype) This prototype game has been disassembled by Richard Degler. The prototype is 2K compared to the released version which is 4K. Comments from Richard made on June 15, 2014: "Counting two additional blocks of unused data/code, the total is 1100 bytes remaining in the released version. In the DEMO prototype, only THREE Invader bombs are active at the same time, and they do share the Player's straight shot pattern. The LEVEL is handled as if it were limited to 1 - 4 just missing the descriptions, and the Invaders are taller, resulting in the flickering feet of the middle rows. The UFO comes out slightly less often, but the scoring is still RANDOM 1- to 3- hundred points per hit, without displaying it next to the (missing) explosion." |

1. Star Battle, (Ready to Assemble) 2. Star Battle, (PDF) | Star Battle This source code is for the Bally cartridge "Star Battle." The cartridge has been disassembled by, possibly, Tom Woods in 1979. As it was included in the Bob Fabris collection without any notes to who actually did it, it is impossible to know for sure. The source code, including cross-reference and an opcode listing, is 30 pages. In December 2011 the "Star Battle" ROM was disassembled and is available in text format. It is ready to assemble and will match 100% with the cartridge ROM. The cartridge was disassembled from scratch and it was only after it was nearly finished that the PDF version of the disassembly was consulted. The text version is probably the preferred version for many people, but the PDF does have some additional comments to offer. |
| Stranded on Rigel 5 (Text Assembly File) | Stranded on Rigel 5 This Bally BASIC program is from ARCADIAN, 4, no. 7 (May 7, 1982): 72-73. It has some machine language routines in it and Richard Degler disassembled these routines. The information that he gleaned from his investigation was used to create a quite extraordinary assembly file. This file will NOT assemble into the original program in any way, but it gives SO much information about how "Stranded on Rigel 5" works. |
| STWEEK, (Disassembly and More) | Stweek (Sound Tweeker) Stweek was never officially released. Word has it that Scot Norris used this for programming sound for the DNA (BALLY) carts. This is a very commented disassembly by Richard Degler. This 23 page zip includes: 1) STWEEK Manual - Written by Richard Degler 2) STWEEK.asm - A complete disassembly of Stweek 3) Stweek_Discussion.txt - Posting compilation between Richard and Adam Trionfo. 4) Two songs that can be loaded in MESS. |
|
Treasure Cove (Complete) - Text. Treasure Cove (Preliminary)- Text. Treasure Cove (Preliminary) - Scanned PDF |
Treasure Cove The "complete" source code is a disassembly of the "Treasure Code" game based on the "preliminary" version. This version matches 100% with the game ROM. The "preliminary" version is the 27 pages of source code for Treasure Cove, as supplied by Brett Bilbrey, the programmer of the cartridge. This preliminary version is not the final version (that source code is not available). The preliminary source code has been retyped and is available in a text version, but it will NOT run (see the file for details). |
| Video Storybook (Partial Disassembly) | Video Storybook Richard Degler finished disassembling the Astrocade unreleased cartridge "Video Storybook" as far as he plans to take it. There are still a lot of Variables and Routines that are left unidentified, but someone filled up an entire 8K ROM with some pretty twisted code, leaving only 132 bytes at the end. |
| Wizard of Wor | Wizard of Wor (Arcade Game) This is 373 pages of source code in assembly language for the arcade game "Wizard of Wor." This is not the cartridge version of the game for the Bally / Astrocade. |
