I'm trying to enable cheats on the SNES core, and it looks like the file is there (for Super Mario World in particular), but the menu item is grayed out in the OSD. Does anyone know how I can debug?

Re: SNES Cheats
Check that the path (directory and file name) is correct, see https://github.com/MiSTer-devel/Wiki_Mi ... gine#setup.
Do you use some special setup such as zipped rom files or external usb storage?
Re: SNES Cheats
The cheats are definitely there. The folder is named Cheats though, not cheats, think that matters? No special setup they were installed when I got it.

Re: SNES Cheats
If you want to debug, the first step is to narrow down the problem. Is it a general problem for all cores? ...or specific to SNES? ...or specific to Super Mario World?

Re: SNES Cheats
Make sure you use the No-Intro roms, they should fit. Unless you use some hacked/translated roms with different names. Then you have manually match the rom and cheat file names.

Re: SNES Cheats
Make sure the rom file matches the name of the cheat zip folder if it doesn’t work. If the two don’t match, either rename the zip or rom file to match the other. See if that works
Re: SNES Cheats
So Super Mario World doesn't have the option unlocked, but Contra 3 does. I went in and changed the cheat filename to match the super mario rom name and CRC but no dice

Re: SNES Cheats
So then one only needs to figure out how Super Mario World differs from the other SNES games. Does the name perhaps contain some special or hidden character? I suggest to manually rename both the cheat archive and the rom file to make sure.

Re: SNES Cheats
The rom from the No-Intro Set = Super Mario World (USA).sfc
The MiSTER cheat zip name = Super Mario World (USA) [B19ED489].zip
So, it perfectly fits. The CRC chechsum in the cheat.zips square bracket is exactly the same as from the No-Intro rom. No-Intro rom+cheatfile names are always a match. Unless you use hacked/translated stuff, as i said before.
edit: If you use the PAL version (not recommend anyway), them manually change both file names to an identical name. This works too, i've tried that. But it could be that the cheats aren't 100% compatible then.
Re: SNES Cheats
OK, downloading a new ROM file that matches that CRC fixes the issue. Thank you very much!
