Oh, I didn't know that. Let me know if you want me to check around stateside. I work in NY, so there are a lot of shops around here that may have obscure components.
Ha, four? That's pretty crazy. Atari never did anything simply did they?
I actually did hack up two Xbox pads, one with a DB-15 female end, one with a DB-25. Each of the pin-points were wired to a button on the controller: A, B, X, Start, etc. I was then able to mod the original emulator controllers (SNES, NES, MD, etc) to work with the Xbox since the controller was acting as a piggy-back of sorts. I even was able to mod a 5200 controller to work, analog and all. This was a major hack job though and its why I also modded a controller with a DB-25 in. I eventually am going to post a how-I-did on here for Madmab complete with picts. I think 75% of the internals were replaced to get it to work.
Anyway, maybe I should just build my own spinner controller (box like) to work with the Xbox in this way? How do those things transmit the signal? The Xbox (and MAME for Xbox, CoinOps) can accept mouse input. I'm able to use the trackball on the X-Arcade in games like Crystal Castles.
Great, I'll keep my eyes open for a 4mb flashcart. I don't want to deal with too complex a setup. From what I've seen the Jaguar CD is really buggy and I'm not sure if there are any really great games that would be worth the hassle. Correct me if I'm wrong!
Thanks again for the support!
