I think "Game Specific" would be EXACTLY that, SPECIFIC to the game, such as a particular fault/mod to a game that probably isnt on all other games - spinning motors, magnacoil, certain plastics etc.
Keeping a log of Rom versions & info would go in 'game specific' for example.

Perhaps the very First 'sticky' post (by admin as they create a new thread title) would be a brief tech-overview of the game info/features (a condensed copy/paste form the ipdb info or something).

Something like:

########################################
GameTitle
Year: 1988
Latest Rom(s): L1-v1.02, L2=v1.00, Sound=V3.01
other: ??
########################################

Generic WPC boards, P.Supplies etc etc would still go into their tech areas etc.
