Pec Gameshark codes for MegaMan 8 not working.

Hello. I am using ePSXe 1.9.25 with Pec v. 3.2.2. The game is MegaMan 8 (USA) and the codes are for this version of the game. Most of the Gameshark codes work but there are some that do not. Some such as "Ultra Mega Rapid Fire" and "Mega Jump". The code I want to use is Mega Jump but it won't work for some reason. Here is the code:
