Sorry for the delay in the follow up. Id already decided on targetting something along the lines of 1200+030+8meg fast, as giving it some thought anyone with a beefy system would be better served to just use mame (or similar), but reading comments people have made just reinforces my decision. A "real" programmer could probably get a near to perfect recreation with less, but so long as I can make it playable, and look reasonably accurate (minus parallax, etc) Im happy.
Sorry, but I dont have my flashdrive with me at the moment, so I'll have to post screenshots next time. Just thought Id make a quick post to let anyone interested know that Im still working on it. Oh and btw, 6 button pads are supported (just thought Id make a quick note on this as a few people mentioned it)
