Title screen demo crash

When the `KEEP_MARIO_HEAD` config option is enabled, the demo sequences will play through one by one like in the original game until it reaches the 6th (index 5, Hazy Maze Cave in the original US version) demo, where it hard crashes on Mupen64Plus/ParaLLEl64 with the error `MTC0 instruction writing Index register with TLB index > 31`. It works as intended on Project64 and doesn't throw an error; however, I'm unaware whether it also occurs on console or not as I don't have the equipment to properly test it.
