Recently I installed PCSX2 and and iso of MVP Baseball 2005, and after getting it to finally boot up, everything worked fine except for certain uniforms and textures being very corrupted/ glitchy looking, and the game has a fluctuating lag. Almost like Missigno for the pokemon games. Players and all other 3D models are fine but not the stuff on them, I'll let the video speak for itself. I've reinstalled the emulator, downloaded new iso's and made one from my own disk but all have the same problem. Any idea about the cause/ solution of this?
