Well I just wiped the dust of my old rom collection and discovered the discs have given up the ghost. Lessons learned - 1. Cheap media isn't a great choice. 2. Always backup your backups! Anyway, if some kind person would like to pm me a link to the showcase release it'd be much appreciated. If not, I'll be playing 1942, Bomb Jack and Sunset Riders for a while as those are the only roms I've recovered so far!
