---------------------- Genesis Plus GX 1.6.0 ---------------------- [Core/Sound] --------------- * added YM2413 emulation in Master System compatibility mode. * fixed SN76489 noise boost initialization. * minor YM2612 core optimizations. [Core/VDP] --------------- * added accurate emulation of SG-1000, Master System (315-5124, 315-5246) & Game Gear VDP. * added support for all TMS9918 rendering modes. * improved Mega Drive VDP timings accuracy in Master System Compatibility mode. * fixed color palette initialization. * fixed shifted sprites rendering in Mode 4. * modified pixel rendering support (pixel depth is now forced at compilation time). [Core/CPU] --------------- * optimized 68k core (rewrote 68k interrupt handling, removed multiple CPU types support & unused code) for 5~8% speed improvment [Core/IO] --------------- * added accurate emulation of Master System (315-5216, 315-5237, 315-5297) & Game Gear I/O controllers. * added Terebi Oekaki tablet emulation. * improved Mouse emulation (fixes mouse support in Cannon Fodder). * improved Justifier emulation (fixes gun support in Lethal Enforcers 2). * improved 6-Buttons control pad emulation (fixes Duke Nukem 3D) * modified lightgun emulation to use common key inputs for all devices. * 2-buttons controller is now picked by default for Master System games. [Core/MD] --------------- * added copy-protection hardware emulation for some new dumped games (Tiny Toon Adventures 3, Mighty Morphin Power Rangers & The Battle of Red Cliffs). * added Game Toshokan in EEPROM database (verified on real cartridge). * fixed Micro Machines 2 - Turbo Tournament EEPROM size (verified on real cartridge). * modified SRAM banswitch hardware emulation to be more compatible with some hacks. [Core/MS] --------------- * added Cyborg Z to Korean mapper database. [Core/GG] --------------- * added 93C46 EEPROM emulation (Majors Pro Baseball, World Series Baseball & World Series Baseball 95). [Core/General] --------------- * added support for .mdx ROM format. * added Game Gear & SG-1000 ROM support. * added accurate emulation of SG-1000, Master System (I, II) & Game Gear hardware models for 100% compatibility. * updated to new Genesis Plus license (see http://cgfm2.emuviews.com/) * removed DOS port * various code cleanup. [Gamecube/Wii] --------------- * IMPORTANT: cheats, screenshots & save files are now stored in console-specific directories (ex: /snaps/md, /cheats/ms, /saves/gg, ...) * added 8-bit Action Replay & Game Genie codes support (for Master System & Game Gear games). * improved audio/video synchronization for PAL games in 50Hz TV modes (now use VSYNC like NTSC games in 60hz modes). * improved gun cursor positioning accuracy. * improved horizontal scaling & screenshots rendering in H32 mode. * fixed a bug with ROM file extension handling that would affect cheats, snapshots, sram & savestate files. * removed ARAM/injected ROM support (unused). * removed WPAD_ and PAD_ update from VSYNC callback. * increased GCC inlining limits for some speed improvment. * compiled with devkitPPC r24 & libogc 1.8.7. 2011-08-07 17:49:46 +00:00			`#endif /* _SN76489_H_ */`
