It's working for me though.
Does the cheat show up and turned on?
Can you tell us what's your setup? Firmware/CFW Version?
What are you using to enable the cheat?
What's your cheats directory/location?
Did you even overclocked your Switch?
Post a screenshot maybe?
Or maybe your playing on Emulator?
We can't help you if you can't tell us what's on your side.
Oh and yeah, Please Chill.
Can't find any threads about this particular issue on GBAtemp or the wider intarwebz. Saw one video on YouTube that seemed relevant, but it was some dude with the same issue, no solutions offered in the comments. :/
