The stars don't relate to speed. 4* means it is playable on a powerful system, with minor bugs. 5* means it is playable on a powerful system with no gameplay damaging bugs. You may occasionally see black textures etc, though.

You were already given the answer. Your CPU is too slow at stock. You have to overclock.
MGS/Soul Calibur II/F-Zero are demanding games. 3.5-3.8 GHz are needed
Zelda WW is less demanding but needs EFB to RAM. Will work fine around 3.3 GHz.
For SSBM 2.8 GHz should be enough.
