[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. Completes P0032, funded by zorg. 2019-09-18 16:33:38 +00:00			`public _FIVE_DIGIT_POWERS_OF_10`
