Hi Bunsen, yes for Plus Too I referred to the code in MESS, Mini vMac, and a couple of other emulators. Another Mac hacker also sent me some code from a similar project he did, which was very helpful.

I'll try to gather up all the design files and code for Plus Too and Floppy Emu and post them to my blog this weekend. That way someone else could take a shot at extending them if they'd like to.

Yes, I'm at OUYA as head of engineering or CTO or something like that (titles are intentionally vague). We ship first hardware at the end of this month. My job is mainly about the software development end of things, though.
