r/u_Struggling_Ladybug

Mario Tennis ultra smash on Cemu Wii u, Ayn thor. Guys i need help wtf is going on

I’m starting to think i might be the problem. I tried updating it, it wouldnt let me. I added shaders and everything you can think of i changed to a Kimchi driver too but it still wouldnt change. The only other game I struggle with here is Rayman Legends. The other games run fine. Im wondering if it could be a problem with the rom itself. I downloaded them Via Wiiudownloader. Is there anywhere else i could try downloading decrypted/wua format Wii U Roms?
