So I’d buy a motherboard used and hope it works?

I did clean the entire system and had it all apart. I also cleaned the game thoroughly. Is it possible to just purchase on eBay a CPU and replace it only?

Game is the right region. No unfortunately I don’t have another console. I could buy one on eBay but afraid it wont work either?

Sorry if this in the wrong forum. I have an original SNES and having issues with 2 separate copies of Super Mario Kart. The games loads and goes threw the menus just fine. One you start a race the track disappears or gets small. Any idea on a fix? All my other games work flawlessly. I bought another cartridge of the same game and same issues... Any help is appreciated. I have included a photo of the issues
