Some people here have created custom themes and firmware for the ez flash. Some claim to have updated gameboy emulator versions, others fix bugs and crashing and even claim battery performance tweaks. So I am wondering, what is the general consensus best of the pack. I always used the default latest ez flash firmware but after I lost all my gamesaves which prevented me from loading new games with no save states created I heard that potentially some of these custom firmwares fix this issue I faced so why not give it a go right?
