mapper 002 - workaround for "Top Gun" issue #621, need test if this isn't broke something other mapper 012 - added hardware dip for language select UNIF PEC-586 - fixed render finally, added 512K cartridges suppport, TODO: PEC keyboard 2013-09-15 10:41:42 +00:00			`extern uint8 NTARAM[0x800], *vnapage[4];`

fix for new-PPU debug information (address and pixel) 2015-01-28 18:12:06 +00:00			`uint32 FCEUPPU_PeekAddress();`
- fiddle with nametable viewer to display correct NT,CHR,ATTR data in more cases (specifically, including some exotic mmc5 cases). - fix a new bug in windows build which caused fourscore emulation to fail in some cases 2008-08-08 09:45:34 +00:00			`uint8* FCEUPPU_GetCHR(uint32 vadr, uint32 refreshaddr);`
fix extended attributes in newppu better, and fix old ppu's chr banking to match newppu maybe? 2017-04-29 23:03:35 +00:00			`int FCEUPPU_GetAttr(int ntnum, int xt, int yt);`

newppu savestates as well as a bit of jacking around for performance and other misc things I meant to do, but alas speedups wont be possible without obfuscating the code. 2009-08-06 00:51:29 +00:00			`#ifdef _MSC_VER`

newppu: fix mappers that used PPU_hook, a truly haphazard system. I am calling PPU_hook far more often than the old ppu for these games, but i would expect the PPU_hook handlers to be resilient against that. 2009-08-11 06:15:06 +00:00			`extern uint8 FASTCALL FFCEUX_PPURead_Default(uint32 A);`

Overclocking. Implemented by adding extra scanlines to PPU loop. Disabled (optionally) while 7-bit samples are playing (as they can't be worked around otherwise). 2015-06-16 19:52:49 +00:00			`extern bool DMC_7bit;`
