I second this. I really like the idea of pdaxrom, but I've been using cacko as I had problems with rc4 (that have been solved, according to most reports). While I have an nes and an snes emulator running on cacko, I'll be damned if I can get a genesis emu working.
I'd like to switch back to pdaxrom to try it again, but I'm playing the waiting game right now. I want to see some stuff compiled for it and see if there's some performance improvements (and right now, that's all beyond my capabilities, so I'm patiently waiting while others do it). Working emulators would decrease my waiting time significantly.
