Description :

Batgba is our Gameboy Advance Emulator. The current version can run almost all demos, and maybe some commercial games.
This tool is designed mainly for the developers which do not have access to the official development kits of the GBA.
The official site is http://batgba.zophar.net.

Recquirements :

You need win9x/NT/2K/XP and directx7 or later.
We have used a portable architecture, and C/C++ langage, so it will be soon available on others OS.
A fast processor (800mhz or more) is highly recommended, especially if you are using the debugging features.
You need also Gameboy Advance roms (".GBA ".AGB" or ".BIN" files) in order to run it, check the net for them.
