Sorry for taking so a day to get back to you.
My Spec ...... I've got it working.
What i've done is to open the location and then create an empty ultimatefullscreen.mfx, I then copied this into the data folder.
I then realised that there are 2 exe files, one in the root and one in the data folder so i've ran both exe's and the game now runs BUT it only fails when I click the "Launch" button in the itch.io app
I'm pleased it's now working but it's strange that the "Launch" button should cause it to crash. I wonder if it's an issue with the path's?
If you want to remotely log onto my box via teamviewer or if there is anything else I can do then PM me. I'm really not worried about this rigging getting corrupted as it's purely for gaming. There's no personal stuff on it.
I'm going to make a video.
