The Yakuza 1 and 2 rereleases on the Wii U export function symbols,
preserving their names, and some debug data was also available in a PS2
release, providing some struct definitions. These have been used to
rename analogous classes, functions, and member variables to the same
names used by Smilebit, plus a more general imitation of their naming
and typing conventions (i.e. Win32 style).
