Which works in both Borland C++, Open Watcom, and Visual C++.
Not that we're about to port any of the games to these compilers, just
something I noticed while evaluating 32-bit compilers for ReC98's own
32-bit pipeline tools. Modders might want to look into that though,
since 100% position independence also makes it easier to change
compilers.
"Physics". Not only did ZUN restrict the X velocity to the 5 discrete
states of -8, -4, 0, 4, and 8 (because hey, unaligned blitting is slow
anyway?), but gravity is also only applied every 5 frames.
We're still missing quite a bit of usage code, but these are the core
functions. One of which turned out to be undecompilable, due to… a
rigorously defined instruction order when performing arithmetic between
`double`s and `float`s?! Still, spelling out all this stuff in ASM
seems much better than somehow splitting the data segment, just so that
we can immediately use literals there.

Yes, TH01's memory info screen will recurse into itself for every 3
frames the PgUp key is held, requiring one additional PgDown press per
recursion to actually get out of it.
You can, of course, also crash the system via a stack overflow this
way, if that's your thing.
