Some PlayStation games released after 1998 contain some form of copy protection/anti-piracy measures, in order to curb modchips and illegal copies that were instrumental in the spread of piracy on the system. Sony developed two systems for protecting games. The first one is Anti-Modchip, and the other is LibCrypt.

Anti-Modchip protection works on the hardware level and is pretty straight-forward. As earlier modchips were active by default through constant injection of region data during bootup, all that it needs for the game to detect one is for the game to return data from a modchip when requested. If it returns data, the game shows an error message screen telling the user that the console may have been modified (i.e. has a modchip). The moment it shows the screen varies from title to title, but it usually happens shortly after booting a game. Early versions of this protection only had a sign with a red hand, hence the Japanese naming for this copy protection: "Red Hand Protect" (レッドハンドプロテクト, reddo hando purotekuto) or RHP for short. Later versions have a "No go" sign with a message in either Japanese or English.

A modded system allows for a backup, a pirated copy, or a legitimate copy of the game from a region different than the console, to start normally. However, with Anti-Modchip or LibCrypt, the game can crash, freeze or perform tricks to prevent pirates, depending on the title.

In Robbit Mon Dieu's case, if the game detects that there's a modchip installed in the system, it will show this error screen shortly after boot-up.
