I have ultimate doom on 5 -3 1/2 in floppies. Disk 1 seems to have lost it's data sitting on shelf for years. I am a newbie so I don't know what mods, wad files, or souceports are. All I know is that I need the data thats on disk 1 in order to install the game. It is DOS based and I believe disk 1 has the exe file on it among other data. will someone take the time to help me? PLEEEEEEEEEZZZZZE!!!!!!
