	About
	-----
	
	Gebea is a plugin-based Gameboy Advance emulator for x86/Win32 computers. It is
	written	in x86 assembly, C and Euphoria. 


	What is emulated
	----------------

	ARM7TDMI	Most ARM and Thumb opcodes are emulated, but not always 				correctly. Register banking does not work at this point.

	Video		Mode 0, 3, 4 and 5 are emulated. Only BG0 is supported in
			mode 0, and only 256-color tiles.
			Vcount and the Vblank flag are emulated.
			Mosaic effects on BG2 in mode 4 are emulated.
			Rotation and scaling is emulated in mode 5.

	Audio		Nothing.

	Input		All keys except for select, L and R are emulated.

	DMA		DM1, DM2 and DM3 are emulated in direct transfer mode (no
			interrupt driven transfers).
	
	Timers		Timers 2 and 3 in prescalar mode.
	

	Keys
	----

	D-Up		Up arrow
	D-Down		Down arrow
	D-Left		Left arrow
	D-Right		Right arrow
	B		Z
	A		X
	Start		Return

	Esc exits the program, Del sets it to idle state and minimizes it to the
	tray.
