First off, current version only supports 2.0 firmwire with a 2.5 version coming later.
Second, backup your save file and then put the edison save file in the Save data folder and then start the game.
After it loads or at any point when your playing press Up + L1 for the special menu to come up. Scroll down and there should be a option to set the processor to 333 Mhz.
60 fps FTW!!!
