Well, here's how the situation is now:
OnimuPC.exe 1.0 orig - Securom v4.8 + CD check.
OnimuPC.exe 1.0 iNVFX - CD check only.
OnimuPC.exe 1.02 orig (patch) - CD check only.
I was going to rip over the protection from 1.02 using the iNVFX.exe and the TECHNiC patch and the HexCmp program. I would've applied the differencies to 1.02 exe. One problem. I DON'T have the iNVFX exe.
Here's the 1.02 patch. The exe displays the CD demand (obviously, because with the disc inside, when I click OK, it passes) even when left out of the game dir totally alone. It needs NO files from the game.
