main.cpp

SNES game emulator. C and asm files.

/*	MAIN.CPP - Main module.
	Ah, protected mode!  I love it!  I can have variables as big as I want and allocate
	4 MB memory chunks without so much as an swap-file manager.

	Command line arguments:

	<filename> - automatically load the specified ROM.
	-Ta - Specifies ROM type (to bypass the autodetect). These apply only to the
		  ROM also specified on the command line. 'a' is one of these:
		  H - ROM is assumed to be HiROM
		  L - ROM is assumed to be LoROM
		  I - ROM is assumed to be in interleaved format (interleave format support
		      NOT implemented since I don't know how to recognise or decode it.)
		  N - emulator will pretend it is a NTSC system
		  P - emulator will pretend it is a PAL system
	-Im - Video mode of user interface
	-Gm - Video mode of game.
		Video modes:
		1=Chained mode Q (256x256)
		2=Chained Mode 13H (320x200)
		3=Original Mode X (320x240)
		4=GUI Normal (360x240)
		5=GUI Tall (360x360)
	-B - Graphics Benchmark: tests all video modes speed of clears and pageflips
