---------- * added Mega CD / Sega CD hardware emulation (incl. Sub 68K, CDD, CDC, PCM, GFX rotation/scaling, etc) * added .ISO & .BIN CD image file support * added 512K backup cartridge RAM support * added savestate support for CD games NOTES: ~~~~~~ * to play CD games, original BIOS ROM files are required in /genplus/bios/ directory: unzip & rename them to bios_CD_U.bin, bios_CD_E.bin, bios_CD_J.bin * CD audio tracks (CD-DA) are not supported (yet) [Core/CPU] ---------- * modified 68k core for Mega CD / Sega CD support [Core/VDP] --------------- * improved DMA accuracy * added support for 8-bit VRAM writes with undocumented code value (verified on real hardware by Nemesis) [Gamecube/Wii] --------------- * modified Master System & Game Gear "BIOS" support (files should be named bios_U.sms, bios_J.sms, bios_E.sms & bios.gg and copied to /genplus/bios directory). * replaced "Hard Reset" button by a Soft Reset for systems having a Reset button (Mega Drive / Genesis & Master System) * State & SRAM files are now only compressed when saving to Gamecube Memory Cards * various fixes & cleanup.
