-Save/Load Method set to Auto - will automatically determine method (NOT YET IMPLEMENTED - defaults to SD for the moment) -All ROM, SRAM, Freeze, and preferences are saved/loaded according to these preferences -new cheats menu! Loads .CHT file from /cheats folder, must match file name of ROM -combined SRAM / Freeze Managers into new "Game Option" menu -SRAM / Freeze - game (re)loaded automatically after loading a SRAM or Freeze from Game Options -SRAM load/save defaults to ON -Game Options, Return to Game, Reload Game do not show up until a game has been loaded -added ROM Information page to Game Option menu -licence/credits moved to Credits page -menu code tweaks -USB support -added future support for Wii DVD / Network loading -MultiTap & SuperScope moved to controller configuration -combined/rewrote SRAM/preferences/freeze code - this is now much cleaner and less repetitve - a few steps closer to being workable -a lot of function parameters have been changed and standardized -if preferences can't be loaded at the start and/or are reset, preferences menu pops up -if Home button is pressed when a game is running, Game Menu pops up -a bunch of misc. bug fixes -probably some more things
