I'm using the latest releases for Snes9x, FCEU, and VBA (the "GX" series), and they seem to all have issues with the menu screen (where you browse the list of ROMs alongside the boxart. I have not run into issues running games, saving/loading, etc. The only time I have issues is if I linger on the menu screen for too long. It doesn't matter which emulator I am using; so long as I spend say more than a few minutes browsing through the list of games, the emulators will each freeze up and require a hard reset (holding down the power button). Are other people experiencing the same problem with these emulators?
