I tried BII under Linux, using a fresh xubuntu 12.04 install, I built the binary from the source repository https://github.com/cebix/macemu
, using sdl. I launched it on a 7.5.3 virtual system image running great under BII for windows. BII starts fine, but the mouse movement is very sluggish. Also, some keys are not working. I checked in the Mac notepad and keycaps app and, for example, all the horizontal num keys seem dead. I checked the keycodes with xev under Linux, everything seems correctly mapped in the keycode file (and raw keycode option is enabled) but BII seems to ignore these keystrokes.
I tried with and without JIT enabled. Only difference is that the display is even slower with JIT disabled, but no change for the keyboard issue.
