Boss explosions! And… urgh, I really also had to wade through that overly complicated HUD rendering code. Even though I had to pick -Tom-'s 7th push here as well, the worst of that is still to come. TH04 and TH05 exclusively store the current and high score internally as unpacked little-endian BCD, with some pretty dense ASM code involving the venerable x86 BCD instructions to update it.
So, what's actually the goal here. Since I was given no priorities 
, I still haven't had to (potentially) waste time researching whether we really can decompile from anywhere else inside a segment other than backwards from the end. So, the most efficient place for decompilation right now still is the end of TH05's main_01_TEXT segment. With maybe 1 or 2 more reverse-engineering commits, we'd have everything for an efficient decompilation up to sub_123AD. And that mass of code just happens to include all the shot type control functions, and makes up 3,007 instructions in total, or 12% of the entire remaining unknown code in MAIN.EXE.
So, the most reasonable thing would be to actually put some of the upcoming decompilation pushes towards reverse-engineering that missing part. I don't think that's a bad deal since it will allow us to mod TH05 shot types in C sooner, but zorg and qp might disagree 
Next up: thcrap TL notes, followed by finally finishing GhostPhanom's old ReC98 future-proofing pushes. I really don't want to decompile without a proper build system.
