[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.

Move common directives and includes to a separate include file Note that .386 needs to come before .MODEL, and is therefore not included in ReC98.inc. Causes, um, weird label errors otherwise.

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.

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.

Given the relative insignificance of the features in question, I presume that Amusement Makers must have kept their own, improved fork of master.lib, rather than ZUN having hacked master.lib on his own. Anyway, that doesn't matter. In the end, we still have to reverse-engineer each and every one of these changes, and some of the more complicated functions won't even be reduced before the actual reverse-engineering step of this project. [Binary change] Order of 3 relocations in TH05's OP.EXE.

[Reduction] #700-704: pfopen ... and then I end up copying modified versions into the individual game subdirectories after all, because the changes between games were simply too drastic. (That's also why I'm counting pfopen() itself twice.) Only one slice left now, and then we're done with reduction!

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.

Found no built-in way to just uppercase an identifier in TASM, so apparently we have to spell out the names in both lower- and uppercase. So, let's go back to regular, non-macro PUBLIC / PROC / ENDP code wherever we can – for all functions introduced in ≥TH03, and for everything that takes no parameters. It's simply not worth the trouble. Part of P0114, funded by Lmocinemod.

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.

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.

[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.

[Maintenance] [th01/th02] Split graph_putsa_fx() into its shared parts I did consider not doing this, because "well, can't anyone who's *actually* interested just diff the TH01 and TH02 implementations to figure out the differences themselves", but that duplication ended up feeling too filthy after all. And hey, it's a nice excuse to update TH02's version to current naming standards! 😛 Part of P0068, funded by Yanga.

[Reduction] #422: draw_trapezoid Yup. From TH03 on, ZUN uses a different version of master.lib, containing more features than the last official version 0.23 from May 1995. Given the relative insignificance of the features in question, I presume that Amusement Makers must have kept their own, improved fork of master.lib, rather than ZUN having hacked master.lib on his own. Anyway, that doesn't matter. In the end, we still have to reverse-engineer each and every one of these changes, and some of the more complicated functions won't even be reduced before the actual reverse-engineering step of this project. [Binary change] Order of 3 relocations in TH05's OP.EXE.

[Maintenance] Distinguish between Shift-JIS and gaiji strings The main point of the previous strings/ subdirectory was to bundle all hardcoded strings for translators. And sure, *technically*, gaiji strings are *both* strings *and* something you might want to translate. But mainly, they're sprites with an attached enum, and their own directory. Changes to the enum quickly tend to involve changes to the strings that use these values, so it makes sense to keep both in the same directory. Especially since 82% of the previous strings/ directories consisted of such gaiji strings. That leaves the strings/ directory rather empty and nondescript though. Recently though, I've been wanting to generally move all Shift-JIS text to this directory. While that wouldn't *solve* the typical "text editor accidentally a file upon save, due to wrongly detected encoding" issue, it's at least a mitigation: If all Shift-JIS strings are in files that contain nothing *but* Shift-JIS strings, a wrongly detected encoding becomes immediately noticeable. For that job, strings/ can have a more descriptive name though. Hence, shiftjis/. Part of P0141, funded by [Anonymous] and rosenrose.

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.

[Reverse-engineering] 32-bit VRAM plane pointers I've looked at every openly available piece of PC-98 documentation, and there don't seem to be any official names for the individual planes. The closest thing I could find was the description at http://island.geocities.jp/cklouch/column/pc98bas/pc98disphw2.htm explaining that they represent the blue, red, green, and brightness component when using the default PC-98 palette. However, these planes correspond to nothing else but the 4 individual bits of the final index into the color palette, and you can assign any color to every single palette slot. Therefore, it's merely a convention that your own palettes don't have to follow (and in Touhou, they don't). Nevertheless, there doesn't seem to be an alternative, and the Neko Project II source code uses the same B/R/G/E convention, so I'll go with that as well.

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.
