Hey there,
I hope it is okay to use English. I thought about using the google translator, but I think it will make me sound even weirder. Anyway:

I am playing on 1.2 and am using these three mods:

Widescreeen Fix: https://thirteenag.github.io/wfp#mafia
Water Shader: https://github.com/ThirteenAG/MafiaWaterShaderMod
XboxRainDroplets: https://github.com/ThirteenAG/XboxRa...of-lost-heaven

They work perfectly together. I also would love to use the MafiaCountrysideMap2.0 which you can find for example in the Mafia Community Modpack. I cannot get the mod to work with the other 3, even though the d3d8.dll from widescreen fix has an asi-loader included.
Does someone here have an idea? I tried asking in another mafia forum, but had no luck.

Hello,
We have same problem and still no solution.

You can choose
Widescreen Fix + Shader Water + XboxRainDroplets
or
Widescreen Fix + Shader Water + MafiaCountrysideMap2.0

That is a bummer.
Well, thanks for the quick answer and let's hope some day someone will find a solution.
