Correct. It just comes with upscaled background pictures and remastered video files.
The steering on PC with no mouse support is as bad as ever. All adventure games used the mouse as input method, GrimFan tried to change that and failed - dumb decision for a otherwise very good game. The 2D backgrounds are in 4:3 as in the original (only the figures are in 3D).
One can play the original GrimFan on Win7 64bit with no issues.
So they remastered the video, but also rerecorded some of the music with an orchestra, and they also redid the textures on the 3d models (e.g., Manny's face), and added mouse support (based on the fan mod).
