Genesis-Plus-GX/source/input_hw/input.c
EkeEke 28775cc3aa [Core/SCD]
----------
* 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.
