[Request][PS1] Chaos Break (SLPM 86363) Widescreen code not working?

[demilich]

I'm trying to run this widescreen code I found for Chaos Break NTSC J on a NTSC U Playstation SCPH 7501 console using an Action Replay Cheat module, but for some reason it is not detecting the code or running it, it goes to a black screen. (However, it does run without any codes activated.)

Could it be because it requires a Master code?

On the other hand, I have been able to run a similar widescreen code for the PAL region of the game and has successfully run. Even with the PAL to NTSC code in the archive here.


The image below is from ePSXe showing the NTSC J region and modifying either of these 2 addresses.
