I got f2 AND restoration, working on win98 with 64 mb of ram… I dont know what the problema might be. RP uses and requires a f2 hd texture patch (included) so thats not the issue.

if you’re using a 64-bit version of Windows (Vista or 7), you may find that the default configuration crashes upon load. You must run the game in DirectX Mode 4. In ddraw.ini in the Fallout 2 directory, find the [Graphics] section and use this setting:
Do not disable DirectX mode in the Sfall settings of the “scrn” preferences in-game, or it will crash again upon startup
