I tried the Flatout 2 test dummy files in my unpacked FOv3 mod for Flatout 1. Swapping in the German version.ini file, FOv3 mod loaded and ran fine. But when I swap in the crash test dummy files, game crash when I started the race.
I'm thinking it the Flatout 2 female.bgm and male.bgm files crashing the Flatout 1, since these two files are 69 KB and the Flatout 1 female.bgm and male.bgm files are only 58 KB.
So if you want the crash test dummies in Flatout 1, you going need the Flatout 1 files it would seem. We did have the Flatout 1 crash test dummies files at Flatout Joint, so maybe someone around here still has them. How about you Heddly?
I tried Google search for > Flatout germany.bfs <, this the file you need for the Flatout 1 crash dummies and could not fine a working download link.
