[Regression] Explicitly request 16-bit default segments when using .MODEL Whoops, turns out that the build has been broken on TASM32 version 5.3 (the one in the DevKit) ever since 7897bf1. In contrast to version 5.0 (which I use for my development), 5.3 actually defines 32-bit segments if you specify a .386 CPU before using .MODEL. That might have been the reason for the .286 workaround all along? Turns out there's the USE16 modifier, which makes this much more explicit than switching CPUs.

Include RULES.ASI from every executable's dump file. Having thought this over for a while, I've decided to stay with the "include slice" model for now, due to various bugs and other reasons. We need to compile for the 386 CPU, but this causes TASM to automatically default every segment to 32-bit mode, which of course is not what we want (and no, .MODEL USE16 sadly does not help either). Appending USE16 to every segment declaration in all included files seems to work, but for some reason, this messes up certain jump instructions. WTF? And even if it did work, we would still have to do this for every single file we include. The alternative would be to build proper libraries and let the linker merge all the code. This would add a lot of unwarranted complexity to the build process. Not to mention all the EXTERN statements we'd have to maintain. Ultimately, all of the C runtime ASM code is going to vanish anyway once we've completed the reduction step. Once we're there, we can simply link to the original version of the library. These initial dumps are not pretty, and I see no point in wasting time on making intermediary stages of development look pretty. Since including RULES.ASI from every slice seems a bit inefficient (and even potentiall harmful, considering the age of the development tools we have to work with), we'll only include it once at the top of every main dump file.

And for TH04 and TH05, it turns out that we not only *want* to move the entire _TEXT segment into the new unit to keep the amount of `extern` declarations to a minimum, but in fact *have* to because of graph_putsa_fx()'s fancy labels in the data segment.

[Maintenance] Use the same resident structure pointer name for every game The TH04/TH05 BGM/SE mode setup is a good example for code where different structure field offsets will vanish completely upon reverse- engineering. If we continued to use the per-game ID string as the variable name, we'd only have another game-specific "difference" there. Part of P0065, funded by Touhou Patch Center.

[Decompilation] [th05] snd_bgm_measure(), snd_delay_until_measure() Umm… but this can't be in the same translation unit as frame_delay(), because OP.EXE has cdg_put_nocolors() inbetween, which means we'd have to compile it twice. What probably happened there: ZUN originally wrote this in C when frame_delay() was still next to it, then generated ASM from it, tinkered with that, and ultimately only linked that ASM into the final game, with the NOPCALL still in there. That might very well be the one temporary NOPCALL workaround we can never get rid of… Oh well, at least we got lucky with the padding, and can keep the cdg_put_nocolors() decompilation from the last commit.

[Maintenance] [th03/th04/th05] Split OP.EXE into two assembly units Wow, that was unexpectedly painless – even for TH03 where we have to deal with a significant number of un-RE'd pieces of data. And for TH04 and TH05, it turns out that we not only *want* to move the entire _TEXT segment into the new unit to keep the amount of `extern` declarations to a minimum, but in fact *have* to because of graph_putsa_fx()'s fancy labels in the data segment.

Remove IDA's cross reference comments We're going to rename *everything*, and grep is a much more useful tool to achieve the same.

Set up labels to denote the BSS and init/exit table segments Again, we can't split dseg into the "real" segments just yet, because that would force us to correct the assumed data segment in every single function. [Binary change] Relocations in TH01's FUUIN.EXE. Again.

Finally use standard segment names everywhere And I guess we just have to ignore and disable that segment alignment warning for TH01. It's not like this changes anything in the binary.

Start out with th05's OP.EXE This is the raw output of IDA's initial analysis of the original OP.EXE, touched up in order to compile to an executable identical to the original build.

Let Turbo C++ link in the Borland C/C++ runtime for the main EXE files This took long enough, so we're not covering the COM files right now. Like, I can't even tell how you're supposed to work around the forced word alignment for the _TEXT segment. Guess we'll just have to decompile all of these in one go, just like we did with ZUNSOFT.COM. Also, it really seems as if we're merely trading one ugly workaround for another in our quest for identical binaries.
