There's always PPC for that.
Weirdly I've been running Cyclone on Pocket PC, and it's performing very strange - sometimes it can do a (megadrive) 16.6millisecond frame in 1.7 milliseconds, but sometimes it goes up to 20.0 millseconds.
e.g. here is timing for ONE opcode - MASSIVE fluctuation in how long it takes

I think it might be due to the memory, but I'm not sure. GP32 may be slower, but it's memory is all fast. In that case GP32 might be a better place to profile Cyclone - because it's a more simple system
Anyway, bit of a disappointing weekend in the end - I was hoping to sort out all the remaining issues with Cyclone and also sort out my own MD emu, but there's still stuff remaining
Here's the games which are missing Opcodes now.

So 4 or 5 opcodes there, and checking the existing stuff of course. hmmm - yeah, wish I'd got futher this weekend
