OK, just completed my Sega romset. Trouble is that for every game, there's like a dozen different titles, with all of the various different GoodTools tags. It's overwhelming and will puzzle anyone who tries to play that isn't familiar with the naming conventions.
What I'm wondering is this -- can I delete the various hacks and alternate versions, or move them into a different folder, without having a negative impact upon the ability to play the game? For consoles, all of the rom images are free-standing, right? (i.e., there are no parent or clone type-relationships where are certain file has to be present to run another one)
