My understanding is that most cheats for retro consoles are a memory location plus a value to write in that location.
I believe that’s how the “game genie” worked on nes, snes, and OG game boy. Have you tried entering some game genie/game shark codes in the RA cheats for your core?
It’s been a while since I used cheats on RA other than save states and rewind but I know I’ve gotten them working before (years ago) on snes
Folks like me that were and remain unhappy with OW2 don’t miss 2016 OW1, we miss 2022 OW1.
