GreenBoy Attack V0.5 - Made for the GBAX.COM 2005 competition.
--------------------------------------------------------------------------------
This is a Green Beret, Rush'n Attack & Mr. Goemon - Arcade emulator for the GBA.
It has bugs in the sprite rendering, no tile priority, and no screenflip
support. You should still be able to enjoy the game though. =)

--------------------------------------------------------------------------------
How to use:
--------------------------------------------------------------------------------
First unzip gberet.zip,rushatck.zip and/or mrgoemon.zip into the same folder
as the emulator.*
Then run one of the .bat files to compile the roms and the emulator.

When the emulator starts, use Up/Down to select game, then use
B or A to start the game selected.
Press L+R to open the menu, A to choose, B (or L+R again) to cancel.

Controller: 2P is only used to start a 2 player game.
Unscaled mode:  L & R buttons scroll the screen up and down.
Scaled modes:  Press L+SELECT to adjust the background.
Speed modes:  L+START switches between throttled/unthrottled/slomo mode.
NOTE: Green Beret/Rush'n Attack is supposed to run at 30FPS.

Sleep:  START+SELECT wakes up from sleep mode (activated from menu or 5/10/30
minutes of inactivity)

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

Advanced:
--------------------------------------------------------------------------------
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.

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 this line to
the pogo.cfg file:
rus 1 greenboy.gba 2
or
rus 1 greenboy.mbz 2
