The only available CD rip of the French version uses copy protection. Because of this, the disc image (MDS/MDF files) needs to be mounted for the game to launch. MDF is a proprietary format that belongs to Alcohol Soft, so Alcohol Portable or Alcohol 120% are required for mounting the disc image. Alcohol Portable is recommended if you do not own Alcohol 120%.

While there may be other programs out there that can mount MDS/MDF files, they may not be able to mount them properly to perfectly emulate the copy protection. WinCDEmu is one of these programs that do not work.
