Using the RetroPad
the Mac OS X build of FakeNES 0.3.1 is under the
impression that it is constantly receiving left
directional input. All other buttons (B, A, Select, and
Start) can be programmed and respond correctly. Right,
Up, and Down directional input works properly as well.
I'd be happy to offer any assistance or donate to the
project to correct this issue.
Otherwise, the emulator performs flawlessly.
