EFB2Texture pretends to copy the EFB to RAM, and then watches texture addresses to see if the EFB gets passed back as a texture. It works if the game only uses the EFB as a texture and doesn't modify it. EFB2RAM actually copies it to RAM, because the game actually is going to do things with it from the CPU (generally).
Overclocking might help in co-op, where the game does actually lag on the real Wii, but I'd think for a game this slow you'd be better off underclocking.
