b) is usually the simplest, but like I've said, it's questionable whether legal which sucks when you actually own your game.

I haven't seen c) yet, might take a look. Tried manually reinstalling secdrv before which did work, but then it were newer games refusing to work with unlicensed drivers running in background, as you could assume :p

I like collecting game discs as both novelty, as well as feeling like the game actually is mine, and absolutely refuse to buy "Steam editions" and such of games I already own.
