--------------- * added support for Master System compatibility mode (Z80 ports access mode), incl. Mode 5 rendering. * added Mode 4 rendering for both Genesis & Master System modes. * added alternate BG planes rendering functions (should be faster on PPC architectures). [Core/IO] --------------- * added support for Master System compatibility mode (Z80 ports access mode). * added Master System peripherals emulation (Control Pad, Paddle, Sports Pad & Light Phaser). * added XE-1AP (analog controller) emulation. * added Activator emulation. [Core/Extra] --------------- * added support for all known Master System cartridge mappers. * added copy-protection hardware emulation for a few MD unlicensed games: fixes 777 Casino (crash when talking to bunny girls). (NB: most of those unlicensed games seem to have been already patched by ROM dumpers, main purpose is documenting them) * added support for Top Shooter arcade board controller. (A=Shoot, B=Bet, C/RIGHT=Coins, START=Start, hold UP on startup to enter service mode) * improved King of Fighters 98 mapper emulation (registers address decoding is now 100% accurate) * fixed Game Genie when several codes affect same ROM address. * fixed EEPROM types for Brian Lara Cricket & NBA Jam TE (verified on real cartridges) [Core/General] --------------- * added Master System compatibility mode emulation (automatically enabled when loading ROM file with .sms extension). * improved savestate stability & compatibility (support for old 1.4.x savestates is preserved) * various code cleanup & comments. [Gamecube/Wii] --------------- * fixed cheat codes handling when several codes affect same ROM address. * improved input controller detection on menu exit. * improved key remapping dialog box to match emulated device * changed Menu key for Gamecube controller to allow MODE button mapping * fixed DVD not being unmounted on swap (memory leak) [Wii only] --------------- * added USB mouse support for Sega Mouse emulation * compiled with latest libogc: improves USB compatibility & fixes stability issues with Wiimotes.
