Ah man, that sucks big time. Especially since Sega CD and 32X games are fairly valuable these days. It's also a pain to get it all back (ignoring the costs) too if you'd want . Do you want to 'restore' your collection?
PS1 games are really not too bad because I can re-purchase them from the PSN store for around $6 each rather then paying over $40 for some games. I'm trying to restore the Sega stuff though but won't do until next gen.
