higan 109

higan is a multi-system emulator that began development on October 14th, 2004. The purpose of higan is to serve as hardware documentation in source code form: it is meant to be as accurate and complete as possible, with code that is easy to read and understand.

higan currently emulates the following systems:

• Famicom + Famicom Disk System
• Super Famicom + Super Game Boy
• Game Boy + Game Boy Color
• Game Boy Advance + Game Boy Player
• SG-1000 + SC-3000
• Master System + Game Gear
• Mega Drive + Mega CD
• PC Engine + SuperGrafx
• MSX + MSX2
• ColecoVision
• Neo Geo Pocket + Neo Geo Pocket Color
• WonderSwan + WonderSwan Color + SwanCrystal + Pocket Challenge V2

I've posted new versions of byuu and higan today.

Changelog:

• Famicom: emulated the X24C01 EEPROM for Bandai-FGC boards (no X24C02 support yet)
• Mega CD: CDC PCM DMA can only write to current bank [EkeEke]
• Mega CD: CDC DMA address setting now clears d0-d2 for proper transfer alignment [EkeEke]
• Mega CD: improve power-cycle handling (not perfect; best to restart the emulator between each Mega CD game still ...)
• PC Engine: trigger VDC coincidence IRQs at start of scanline (fixes Bomberman '94, Air Zonk start screen rendering issues)
• PC Engine: improved RCR interrupt emulation (fixes Air Zonk in-game)
• PC Engine: fix VDC DCR writes (fixes Gaia no Monshou, Magical Chase, etc)
• PC Engine: reduced VDC access delays (fixes Wonder Momo, but may not be hardware accurate)
• PC Engine: improved instruction timing
• PC Engine: added Avenue Pad 6 emulation (higan only for now)
• WonderSwan: window emulation improvements
• byuu: BIOS firmware settings window improvements
• byuu: can now load firmware from inside ZIP archives
• byuu: added trace logging tool
• byuu: added manifest viewer tool
• byuu: add path overrides for saves, BPS patches, and DSP firmware files
• higan: fixed a serious issue with the "Create New System" option from the launch screen
• nall: fixed a subtle yet important issue with Natural/Integer::bit() that allowed out-of-range bits to be set
