Some instructions and registers removed, and a handful of instructions added.. .and possibly even instructions moved around. You'll need a special "GB z80" list.
Here's a page I found when looking for info for a GBS player I was working on:
http://www.devrs.com/gb/docs.php#docsmisc
the 'GB Cribsheet' link on that page I've found to be wonderful and I highly recommend it.. even though it is a pdf file =/ |

I've been thinking about trying to make an emulator (just to see if I have got enough patience, time and skill), and decided to try to make a GB one, since I guess that it's the simpliest one.
