first of all congratulation for your hard work.
Just a little bug report:
Zelda 2 froze the emulator after approximately 1h playing. I couldn't do anything (in game neither activating the emu menu), but I managed to go back to the app select screen by pressing the power button+select (so only the emu froze, not the console).
48khz sound + low pass filter, everything else default.
Since I don't know wether most of you tested the games for more than an hour, the problem may come from that long time playing.
: This bug happened again on faxanadu, every option set to default. I think we definitely need an update for this emu.
