The glacial pace continues, with TH05's unnecessarily, inappropriately micro-optimized, and hence, un-decompilable code for rendering the current and high score, as well as the enemy health / dream / power bars. While the latter might still pass as well-written ASM, the former goes to such ridiculous levels that it ends up being technically buggy. If you enjoy quality ZUN code, it's definitely worth a read.
In TH05, this all still is at the end of code segment #1, but in TH04, the same code lies all over the same segment. And since I really wanted to move that code into its final form now, I finally did the research into decompiling from anywhere else in a segment.
Turns out we actually can! It's kinda annoying, though: After splitting the segment after the function we want to decompile, we then need to group the two new segments back together into one "virtual segment" matching the original one. But since all ASM in ReC98 heavily relies on being assembled in MASM mode, we then start to suffer from MASM's group addressing quirk. Which then forces us to manually prefix every single function call
- from inside the group
- to anywhere else within the newly created segment
So while you now definitely can request any specific thing in any
of the 5 games to be decompiled right now, it will take slightly
longer, and cost slightly more.
(Except for that one big segment in TH04, of course.)
Only one function away from the TH05 shot type control functions now!
