[NES] puNes 0.22

Red Pig (1993)

0.22

• Implemented all illegal opcode.
  
• Rewrite from scratch MMC3 emulation and now really work with every rom that I've tested (for two weeks I've tryed all 5118 MMC3 GoodNES roms including Blargg mmc3 test) except for few bootleg and some chinese roms (why??).
  
• Implemented fix for young indiana jones chronicles (thx James).

0.21

• Correct some bugs in the MMC3 (NTSC and PAL) and now
• all the roms that I'have tried works well.

0.20

• Implemented illegal opcode 0x80 for the "Beauty and the Beast (E) [!].nes" rom

0.19

• complete APU emulation.
• This is my first attempt with sdl sound and perhaps there may be some bugs. For now, without the implementation of frameskip, the emulator has to work 100% for not having problems with sound skip and crackle.
• Changed the structure of the code and now the emu takes less than 100Kb.
• Correct many many many bugs.

puNes 0.11:
