byuu says: Changelog: - fixed LYC interrupt at LY=0 (fixes Makai Toushi SaGa) - fixed MBC3 ROM bank mapping (fixes Harvest Moon GBC) - added Super Game Boy MLT_REQ support to JOYP, needed for ICD2-R emulation - temporarily changed System::run() to execute only four cycles before exiting for bsnes, will make two versions later - uses actual boot ROMs, has DMG+SGB1 for now. Need SGB2, don't care about CGB. Defaults to SGB1, no way to select just yet. DMG 4-second wait is annoying. Does not force games to act like SGB on bgameboy itself, because that has no ICD2 and fails the required MLT_REQ check
