GreenBoy GBA

GreenBoy Attack is a Green Beret, Rush'n Attack & Mr. Goemon - Arcade emulator for the GBA.

It was developed for the GBAX 2005 Coding Competition.

User guide

First unzip gberet.zip,rushatck.zip and/or mrgoemon.zip into the same folder as the emulator (filenames are taken from MAME 0.94).

Then run one of the .bat files to compile the roms and the emulator.

Make sure your flashing software allocates 8kByte/64kbit SRAM for GreenBoy.

Note: Green Beret/Rush'n Attack is supposed to run at 30FPS.

EWRAM speed:

This changes the waitstate on EWRAM between 2 and 1.
This can probably damage your GBA and definitly uses more power, around 10% speedgain. Use at your own risk.

Link transfer:

Send GreenBoy to another GBA.
The other GBA must be in multiboot receive mode (no cartridge inserted, powered on and waiting with the "GAME BOY" logo displayed).
Only one game can be sent at a time. A game can only be sent to 1 (one) Gameboy at a time, disconnect all other gameboys during transfer.
Note: Use an original Nintendo cable.

Pogoshell:

You can use the "build_pogorush.bat" & "build_pogoberet.bat" to compile only the roms and use the emulator as a plugin in Pogo.
Copy the plugin (or compress it to mbz before you copy it) then add either one of the following line to the pogo.cfg file:
- rus 1 greenboy.gba 2
- rus 1 greenboy.mbz 2

Menu:

Up/Down - Select game

A/B - Start selected game

In game:

L+R - Open menu

A - Choose

B or L+R - Cancel

L/R - Scroll screen (Unscale mode)

R+Select - Adjust background (Scaled mode)

It has bugs in the sprite rendering, no tile priority, and no screenflip support. You should still be able to enjoy the game though.
