Was working fine for years until recently when I discovered it now boots you from the game you're playing if you turn the phone off. It does allow you to resume where you left off when you turn the phone back on, but only after reselecting the game from the menu. This is incredibly annoying, though, when you have a list of about 50 ROMs, and you have to reselect it every time you turn the phone off and back on. I sent the dev an email about this issue and never heard back.
