I'm trying to write an 68k emulator and I'm wondering about a few things.

* Is there any reference available where I can find how many cycles the instructions take? I couldn't find it in the motorola programmer's reference. Can I cheat here a bit?

* Since I want to use it primarily for arcade emulation, are there some things in the 68k which are almost never used (so I can make life a bit easier at first :-) ?

* What is a good arcade game to start with, so a simple to emulate yet fun machine? So that I won't have to torture myself trying to get Galaxy Force to show anything, you know... :-)

Thanks,
Erik
