−* completely rewrote EEPROM emulation: now support all known EEPROM types (24C01-24C65) and mappers (Sega, Acclaim, EA, Codemasters)
−used in a few games (now use internal game database) as external RAM. This should at least fix save support in the following games:

−* improved Interlaced 2 mode (double resolution) rendering: Sonic 2, Combat Cars ("VS-Modes") look far better
−* added TMSS BIOS support (optional)

−
−[Gamecube]
−

−* added "Overscan" option to disable the original borders color and always use black borders (only used when ORIGINAL Aspect mode is enabled)
−* added support for up to 720 pixels horizontal resolution (needed for proper aspect ratio emulation)

−* removed "CPU Type" option, you can also now force Region (JAP/EUR/USA) without reseting the game, choose USA or JAP for 60hz, EUR for 50hz, this can be useful to bypass game region protection at startup.

− in some games to enable special features or even complete the game (ex: X-Men).

−* modified controls when going into the rom selection menu (DVD or SDCARD):
− . use B button to go up one directory
− . use Z button to quit the file selection menu

−* you can now switch between FM cores without reseting the game. FM registers value are automatically restored when switching.
−* removed the previous VINT timings modification because it brokes some games (Rocket Knight, Thunderforce III,...)
−* added automatic Timing configuration (VDP latency, VINT timing & alternate Line Timing) at game loading, based upon specific romname detection.
−This means you can still modify some of these options afterwards but they are now automatically set/unset when loading a game which need
−special timing fixes. These fixes are also automatically desactivated when the current game doesn't need them.
−For information, games that are actually detected and need special timings to run properly are:
− .Legend of Galahad & Road Rash series (single line not rendered properly)
− .Sesame Street Counting Cafe (don't boot)
− .Chaos Engine/Soldiers of Fortune (graphic glitches on scrolling)
