How can you play a csm mod without using csm? If you restart the computer, and you say you play the same mod, then how are you doing it without csm? If it is a mod, then you must be using csm. Am I right? If the mod loads without csm, then the only explanation can be that the wad has not restored to its original form on csm exit. This can happen when a forced exit occurs and csm is unable to unload the wad. Therefore the wad contents are as they were when csm loaded it. Grand Prix 4 can only load what it finds in the wad.
If it is playable, it could be because not all of the csm content is present, for example the anim wad may not be loaded. That is an assumption on my part, as to the real cause, it could be a number of factors involved.
A black screen hang is definitely a graphics issue as I said earlier.
So, to sum up, when you load a full mod via csm, it hangs, due to the inability of the graphics to correctly render, however, when you restart and run again, only a part of the mod is being loaded, so your graphics can render it. If you were able to exit GP4 without forcing a computer re-start, CSM would unload and restore the wad.
I am at a loss to explain why it runs at all, but it appears that it does. Download the clean wad from my files. Replace the wad, start CSM, run till it hangs on the black screen. Restart again, replace the wad once more, and then start GP4 from gpx and see what you get.
