to play the original maps as a grandpa , simply download a copy of Old Fartenstein 3D , Remove the (Gamemaps & Maphead) files that are already in there , and put the modified (Gamemaps & Maphead) files from the (Original Maps For Old Fart) ZIP in the main Old Fartenstein File , Run the game & you'll have exactly what was seen in this video.
-Enjoy.
P.S...
Can Someone Please make an ECWOLF compatible version Of Old Fartenstein ?
