Config files could be a good idea too, with different possibilities: 720p users, 480p & 480i/Pal users, 16:9, 4:3 users... as we all spent a lot of time trying to get the best results in emulation depending on games & our TV (I think about pcsxbox, surreal64, winuaex: difficult for the newcomers). Edit I mean solid & validated files, not 500 non trustable files per game like we could find on XPort's site in the past.
