Mainly because it isn't fast enough (at least for real-time emulation). I think
it was Scott who wrote a bit about this on A89 some time ago - basically, even
though the TI-89/92 68k @10-12MHz is faster than the GB:s (modified) z80, there
aren't enough cycles for each GB z80 instruction. Maybe dynamic recompilation
could help a little, but it would still not be real-time.
I believe the GB also has special hardware to help it with some tasks. Plus
there might be a space problem, although I'm not sure how big GB games are in
general.
