Copying proper .exe for EU or US version should enough. Although patcher also extracts filter.efx (possibly NOS black screen effect fix) to the patch exe folder if proper game binary or registry entry is not found.
Widescreen patch compatibility not tested.
If all above fail, reinstall the game, and use e.g. 1.0 version (afterwards, replacing exe and filter.efx should enough).
The problem can happen e.g. after Samantha Time Trial 2:07 (hard), on 1.4 binary version, and is gone on 1.3.4.
