nmlgc c5a18ecfa0 [Naming] [th02/th04/th05] Maximum and default starting lives and bombs
Oh wow, caff4fe introduced wrong bytes into RES_KSO.COM by confusing
[cfg_bombs] with [credit_lives] -.- Which I didn't find out back then
because all the RES_*.COM binaries still had some different instruction
encodings anyway and I just didn't care enough to base my diff of those
files on the wrong encoding versions to notice the bug…
Whoops.

nmlgc 042b7802bf [Reverse-engineering] [th04/th05] Resident structure
And yes, you can get it in your own tool by simply #including
th04/th04.hpp or th05/th05.hpp.

nmlgc 5eeed67113 [Reverse-engineering] [th04/th05] GENSOU.SCR structure
Funny how the actual scores are stored as little-endian gaiji strings
in the bold font, yet never actually used as such.

nmlgc deb1b73016 [Maintenance] Use a single DEFCONV definition file to cover all games
This makes a lot more sense in C land, where we can then #include this
tiny file in front of all DEFCONV declarations.

nmlgc c77a9276d3 [Reverse-engineering] [th04/th05] Death-related variables
Including the confirmation that both games have an 8-frame deathbomb
window.
The placement of the variables is all over the place though, what the
hell?

nmlgc f8213c5a32 [Reverse-engineering] [th04/th05] HUD bar display
So it's *_put(), inherited from master.lib, for everything just writing
to text RAM, and *_render() for everything more involved? But what
about master.lib's own graphics RAM functions like super_put()? Need to
fix that inconsistency some day.

Once again no decompilation, because…

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.
