Too bad that alignment constraints do in fact force us to compile
th04/bullet_u.cpp and th04/bullet_a.cpp separately. 😕
Part of P0184, funded by -Tom-.
… (24 + (difficulty * 8) + rank) in TH04, and (42 + (difficulty * 8))
in TH05. Also, TH05 only doesn't have TH04's bullet zap animation
because ZUN didn't consistently use constants…
