Rockboy performance on a Fuze V2

So I've noticed that some games run just about perfectly, like Zelda: Oracle of Ages at around 50-60 FPS and a frameskip of 1-2, but some (particularly GBC games) tend to have a performance decrease. For instance, Donkey Kong Country performs at around 30 FPS with a frameskip of 10. I find it odd that one GBC game would run fine, but another, not so much. Is it simply that the Fuze doesn't have the power to run something as... graphically intense as Donkey Kong Country? (Hilarious as that is.. )

Why is that strange?  Different games do different things, and so the emulator will in turn have to emulate different things.  If its doing different things, it'll run at different speeds.
