I'm trying to port MJOY:
from mega8 to mega88.
Firstly, has anyone done this already?
I've attached my source code and unix-diff file (so you can see the changes I made). I think it's all correct, it assembles and flashes, but doesn't communicate with USB correctly. i.e. Windows gives a USB communication error.
I'd really appreciate any help or tips, because it looks like I'm stuck.
