[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.

[Maintenance] Rename the extension of game-specific ASM includes to .inc Rule of thumb going forward: Everything that emits data is .asm, everything that doesn't is .inc. (Let's hope that th01_reiiden_2.inc won't exist for that much longer!) Part of P0032, funded by zorg.

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.

[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.

[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!

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.
2014-08-17 21:55:59 +00:00
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.

[Reverse-engineering] [th02] Keyboard input Don't really understand the other games yet because they start introducing joystick support and TH03 has multiplayer and then there are these master.lib modifications that don't really make any sense to me, especially when you add that TH04 seemingly does not read js_stat *at all*, yet still works just fine with a gamepad and... urgh.

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.
