snes-dsp1
A clean-room DSP-1, the maths chip in Super Mario Kart and Pilotwings. It gives the original chip's answers without its program, and runs much faster than emulating the chip.
- Matches the original on every probed input for most commands
- One class, two registers
- Both chip revisions
snes-dsp2
A clean-room DSP-2 implementation for Dungeon Master, so emulators can answer its commands without the original chip's program.
- Matches over 12 million recorded game reads
- Data and status register interface
- Command exactness limits documented
snes-dsp3
A clean-room implementation of the DSP-3 coprocessor in SD Gundam GX, answering its commands without the chip's original program.
- Runs SD Gundam GX
- C++17 and save states
- Known data-ROM and path-cost differences
snes-dsp4
A clean-room DSP-4 implementation for Top Gear 3000, with a C++ interface for its data and status registers.
- Runs Top Gear 3000
- Matches 96–100% of recorded reads
- Known hill-crest clipping and rounding differences
snes-st010
A clean-room ST010 implementation for F1 ROC II: Race of Champions, answering the coprocessor's commands without its original program.
- 4 KiB RAM interface and save states
- Recorded game traffic checked against the original
- Known table differences documented
snes-cx4
A clean-room replacement for the Cx4's mathematical data ROM, used by Mega Man X2 and X3. Computes the constants at emulator startup.
- All 1,024 entries match the original
- Six tables generated from mathematics
- Data ROM only; requires a Cx4 processor emulator
snes-spc700-boot-rom
A free replacement for the boot ROM of the Super Nintendo's sound processor, so emulators can ship one instead of the console maker's.
- The same conversation with every game tested
- Ready-made .bin and C header
- Source and assembler included
