This version is cracked (with the crack details below).

Crack

To apply the crack, follow these steps:

  1. Download DiskExplorer.
  2. Use DiskExplorer to extract the file CSBGAME from the disk image.
  3. The original CSBGAME file is compressed with LZEXE. Use UNLZEXE to decompress the file.
  4. Open the file in a hexadecimal editor.
  5. Go to offset 0x0E48C and replace 33 FF 8B F7 56 by EB 59 8B F7 56. This will remove the protection check when you save the game.
  6. Go to offset 0x1492E and replace C7 46 F0 02 00 by EB 20 F0 02 00. This will remove the protection check when you start a new game.
  7. Use DiskExplorer to import the cracked file CSBGAME into the disk image (no need to compress the file).
