nmlgc e6294c2c1a [Reverse-engineering] [th02/th04/th05] Score update and display
The TH02 version is a piece of cake…

… but TH04 starts turning it into this un-decompilable piece of
unnecessarily micro-optimized ZUN code. Couldn't have chosen anything
better for the first separate ASM translation unit.

Aside from now having to convert names of exported *variables* to
uppercase for visibility in ASM translation units, the most notable
lesson in this was the one about avoiding fixup overflows. From the
Borland C++ Version 4.0 User's Guide:

	"In an assembly language program, a fixup overflow frequently
	 occurs if you have declared an external variable within a
	 segment definition, but this variable actually exists in a
	 different segment."

Can't be restated often enough.

nmlgc f07089017f [Maintenance] Rename the extension of game-specific ASM includes to .inc
Rule of thumb going forward: Everything that emits data is .asm,
everything that doesn't is .inc.
(Let's hope that th01_reiiden_2.inc won't exist for that much longer!)
