AmiGameBoy is a Game Boy emulator for AGA Amigas, in 68020+ assembly. It
plays the games of the original mono Game Boy (.gb files) with sound,
battery saves and a CD32 pad. It is written for an A1200 with a 68030/50
and faster machines (PiStorm, BigMig, Minimig, 68040/68060 cards). While
a game runs it takes over the machine and drives the AGA chips directly.
History
-------
Juan Antonio Gomez Galvez began AmiGameBoy in 1996-97; his last public
version was 0.96. In 2026 he sent his sources for the community to carry
on. This community version, released with his consent, keeps his menu
and his AGA display and runs the games on the Game Boy engine of
Wzonka-Lad by Ville Helin and Ventzislav Tzvetkov (GPL-2), which adds
the timer, the memory controllers, battery saves and sound.
New in 1.0
----------
- The Game Boy engine of Wzonka-Lad behind Juan's menu and display: one
program, AGA.
- Four-channel sound on Paula.
- Cartridge types MBC1, MBC2, MBC3 and MBC5 up to 2 MB, battery saves
(.sav beside the cartridge).
- CD32 pad, with the buttons editable in AmiGameBoy.config.
- A cartridge can be given in the Shell (AGA game.gb) or by a project
icon. The Insert requester lists cartridges and drawers only.
- Palettes that change down the screen are followed line by line.
- Full source included, GPL-2.
Requirements
------------
- An AGA Amiga with AmigaOS 3.0 or later.
- A 68020 or better; a 68030 at 50 MHz or faster for full speed.

Installation
------------

Insert, pick a .gb file, then Power ON. Esc returns to the menu. See
ReadMe.txt or AmiGameBoy.guide for the keys, the pad and the saves.
No games are included. You need cartridge images of your own, copies you
may legally have.
Not supported

Game Boy Color-only cartridges (refused with a message), the colour mode
of dual-mode cartridges (they run in mono), the link cable, Super Game
Boy features.
Known issues
------------
