I gave instructions to ryo-sakazaki on how to dump the S1 with his device programmer. After I graciously answered all his questions, he hasn't replied to my last couple of requests for status so I would assume he just wanted to know how to dump the rom and not follow through on his end. Why can't these guys follow through with what they say they are going to do?
Doesn't matter though. I've got a set of MVS slots to use and will start on a cart edge reader after I finish up a couple other things first, and will send this reader off to Rob to get his M1 & S1 once I get that working.
