I recently downloaded both the Linux and Windows versions of VVVVVV 2.0. I used ConVVVVVerter to convert my old (Windows) save to a new (Windows) save, which worked fine. Then I installed the Linux version and copied tsave.vvv and unlock.vvv to my .vvvvvv folder, which successfully copied over my saved game... except for my time trial records. Where are these stored? I can't seem to find them anywhere.
EDIT: Essentially resolved; I found another solution. I may not know where this is stored, but ConVVVVVVerter does, so I simply ran ConVVVVVVerter under Wine, converting directly to the Linux copy. Note this first required installing Mono under Wine.
EDIT again: OK, I guess this topic is obsolete for a different reason than I expected; upon exiting and re-entering the game, the records disappeared, which means that actually this is the same as the problem that Terry is already working on. Sorry about that!
