Instructions

Using a hex editor of your choice, edit the BBT.exe/VT.exe file, and look for the following bytes:

  • BBT.exe: FF FF FF 85 C0 6A 01 7D
  • VT.exe: FF FF FF E8 BF 9D F7 FF

Replace it with the following bytes:

  • BBT.exe: FF FF FF 85 C0 6A 01 EB
  • VT.exe: FF FF FF 90 90 90 90 90 (remove the call entirely)

This will entirely bypass the CD check, allowing you to play without mounting the ISO for this 20 year old game.

Why did I make this? Because it was annoying to take an extra 30 seconds out of my day to find and mount the ISO. I hope it serves whomever happens to stumble on it well.
