Wow... A tech problem with FF7 turns into a removable media debate.
I can tell you this about the TNT patch....
IF 8 bit pallet says PASS, "do not" use the FF7.exe from the patch...and don't check any of the Nvidia option in the FF7config.exe, from the patch.
If 8 bit pallet says FAIL.... You use the FF7.exe from the patch, and select the Nvidia options of the FF7config.exe of the TNT patch.
Not following those rules...will cause the game to not run...from my experience, anyway. Which is outdated, being I haven't played FF7PC for a few years. But, I'm sure it still holds true.
