I’m thinking if you delete the sfall ddraw.dll then it may work. Unknown if GOG made any other changes to their package tho. I’m really against re-buying software I already “own” otherwise I’d grab a copy and see what changes they made.

If you want a more modded version of the game then there is the FIXT mod over at the no mutants allowed forum. If you want just the fixes then grab the TeamX patches (also at NMA). The game is fully completable without but the fixes are nice.

Whoa I’m 100% unsure, but all the more willing to check out!

The gog version. I’m a filthy casual who never played it in 1997, I’ve seen it in stores, just never got around to it for some reason… Well then again in 1997 I was so busy working… Saving money to buy a house I’d ultimately loose. sigh.

I don’t have the GOG but I’ve heard that it uses sfall. Here’s sfall for Fallout 1 https://github.com/Sduibek/sfall_1
