I think that’s just the shader caching being rendered isn’t it? I know totk has some caching that can be pre downloaded but I believe it still is cached when you are running the game. I think it stabilizes after a bit but I had trouble getting ryujinx and yuzu working so I opted for the cemu (wii I) route.

Oh whoops, it was vimm.net. My bad. I honestly wasn’t sure. I figured Google would sort it out for anyone just typing in vimm

Emudeck has a really nice tool to mass convert a folder to .chd and as far as the rims go I usually just go to the mega thread on /r/roms or you can go to vimm.com
