The emulation itself is not perfect, so not all games will run under Frodo. Unfortunately, I cannot do very much about this since I haven’t written the emulator – just ported it. If you have multiple versions of a game, try each of them as often at least one will work. Saves will be stored on the SD card. You can save and load game state. Play Bubble bobble over the network.
