Nebuleon Fumika	b7867f01cc	Memory access optimisations in sprite rendering.	2012-12-30 14:34:12 -05:00
Nebuleon Fumika	d1d0c81af8	Rendering optimisations. ... tile.cpp: Optimise the common case of drawing an unclipped but possibly flipped 8x8 tile. Instead of calling WRITE_4PIXELS16 16 times, each performing setup and teardown, move the loop into DrawTile16. tile.h, tile.cpp, gfx.h, gfx.cpp: End the use of global variable GFX.ScreenColors to pass around the current frame's palette. This saves on memory stores/loads.	2012-12-30 00:20:45 -05:00
Nebuleon Fumika	6b36e79013	Speed up rendering by an unknown amount. ... gfx.cpp, others: Avoid always checking for Settings.SixteenBit if FOREVER_16_BIT is defined. port.h: Define FOREVER_16_BIT below PIXEL_FORMAT.	2012-12-27 18:02:03 -05:00
Nebuleon Fumika	a194b85003	Preliminary Snes9x-based cheat code support. Not tested, because the file selection interface freezes when it gets to the folder containing Mightymo's cheat files, whereas it did not do this before with the converted Mightymo cheats. (335 files -> 679, though.)	2012-12-22 22:16:55 -05:00
