rotation/scaling, etc)
* added .ISO & .BIN CD image file support
* added 512K backup cartridge RAM support
* added savestate support for CD games
NOTES:
~~~~~~

* 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.
