Action 52 (REV A).nes
Alfredo and Jigsaw are playable

Should work with an actual Game Genie and all green PCB versions of Action 52 NES cartridges using original hardware. Although this is an indirect method of fixing the issue, I found this method before figuring out a bad JMP instruction is the reason they hang while attempting to load.

Action 52 (REV A).nes

Select Shooting Gallery to play Prototype French Baker
PESEZYZA
(This is because REV A requires more than 3 codes to fix the collision hanging glitch in order to play the prototype version of French Baker if you are using a real Game Genie and Action 52 green PCB REV A cartridge.)

Action 52 (REV A).nes

Fixes Shooting Gallery, They Came and French Baker Prototype screen exit crashing
I actually forgot that there is a bug in REV A Action 52 that crashes Shooting Gallery, They Came and the Prototype French Baker. Technically you need the second line though the first one only does work.
