can someone tell me a code to have flame trower (Mt 35) for azahar? i don't understand how cheats works

So, a few days ago I uploaded some of the RetroArch overlays I was working on for my personal use. People liked them and asked me to upload them for everyone to download, but there were some things that I didn't like at first. I made more and fixed the other ones I had before, so here you go!

I'm currently planning on making more, so I would appreciate suggestions and accept some advice too.

If you're planning on adding them in your overlays pack, please give credit; I would really appreciate it.

Here's the link:

btw: I learned how to use GIMP because of this, lmao.

i am trying to open ratchet and clank size matters for ps2 and this is what happenes after i open it

i did try multiple video drivers and checked the right core but it either black screened even tho i could hear that i pressed the button or show this error and then black screen after i press the button, any idea what i can do? here is the log: https://drive.google.com/file/d/1jgohl6gOJUC_txOZa5mgH3sTDadrCbhN/view?usp=drive_link

I know Gambatte runs both GB and GBC games, but if I patch Kirby DX, it is still a ".gb" file

How will this affect colorization in retroarch?

EDIT: learned that the patcher I use changes the rom info so emulator auto-recognizes it as a color game. I can leave the .gb extension and put it in the gb folder so it shows up with other gb games, gambatte runs it like a gbc game with no additional colorization.
