titles that share the first three characters of their IDs with
unrelated titles (mostly unlicensed titles and Triforce titles).
Removes speedhacks from metroid prime 1 and 2, and fire emblem series
and update old notes for metroid prime. Capitalize dolphin in the few
inis that weren't from the previous commit.
