Just picked up a very nice, and now working Demo Derby.. Been playing the hell out if it now that I've installed a nice burn free monitor.. But I can't save High Scores.. This one isn't the typical MCR with (3) pcb stack and MCR power suppy. It's actually a Mono MCR which is one pcb with everything built into it, yay no ribbon cables!!
Also came stock with a Condor switching ps, which I've since removed. I've also built an adapter so an off the shelf switcher can be used, no reset circuit!
Anyway.. I'd like to save high scores. I've got a battery mod on my Spy Hunter that works well.. But because this doesn't have a typical MCR ps, and no battery on either the Mono pcb or original ps, was this ever able to save high scores?
