F1 2010 The Game (Codemasters)
To understand for everyone in here, i want to make an 2010 mod for the PSP game F1 2009, the only stuff that i want to import is the tracks and the cars... do i need more than that? My plan is to replace cars and tracks with (lower quality modded textures) and also the drivers! i would be happy for some help!
