My Nes Interface Featurers

General Features:

·         Accuracy, My Nes pass almost all known nes tests by emulating the real hardware behaviors without any kind of emulation hack. 

·         Compatibility, My Nes support more than 100 board/mapper which mean thousands of games are playable.

·         Multithreaded Emulator, the emulation process run in thread separated from renderer threads. This may improve performance especially with multi core cpus. 

My Nes Emulation Specification

  CPU 6502

 All CPU 6502 instructions implemented including the so called illegal opcodes.

  Interrupts

 Implement exact interrupt timings like interrupt check before the last instruction behavior

  PPU

 Implement the Picture Processor Unit as described in the wiki docs http://wiki.nesdev.com/w/index.php/PPU_rendering with exact timing

 Palettes

 Implement the palette generator of NTSC video as described at http://wiki.nesdev.com/w/index.php/NTSC_video

  TV Formats

 NTSC, PALB and DENDY.

  Sound

 Implement all Nes 5 sound channels, MMC5 external sound channels and VRC6 external sound channels, along with sound downsampling using the Band-Limited Sound Buffer "Blip_Buffer" <http://www.slack.net/~ant/ >.

  Sound Playback And Record

 Fixed to 44100 Hz - 16 bit - Mono. Applied for playback and record. Sound record depends on emulation speed not on sound playback so record doesn't affected if the emulator run fast or slow.

  Mappers And Boards

 Implement about 97% of known and documented mappers

  Controllers

 4 players joypads, Zapper and VSUnisystem DIP. Note that you'll need to connect Zapper or 4 Player in settings manually in order to use it
