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 |
