Trick TASM into not creating 32-bit default segments So that's the - admittedly rather weird - solution to the problem that has been plaguing this project ever since the beginning of the reduction step. Without any 32-bit dummy segments in the compiled object files, more linkers will be able to build this project, one of them being JWlink (http://sourceforge.net/projects/jwlink/). Still can't rename dseg to _DATA though, as TASM stupidly refuses to accept any ALIGN directives above a segment's alignment attribute value. TH01's floating-point data slices already require larger alignments, and we're very likely to have even more of those in the future. Also, we're finally defining the Borland C++ model symbols directly in the code, rather than in my unpublished build batch files. :)

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.

Replace MASTERMOD with a per-game constant Yup, packfiles finally proved that we really have a different set of changes to master.lib in every game. Also, there are bound to be more of these game- specific small changes to otherwise identical code in ZUN's own code. And hey, no need to define that value in the build scripts anymore. (I've also considered just copying modified versions into the individual game subdirectories, but it's not too nice to expect people to diff them in order to actually understand why these copies exist and where the changes actually are.)

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.

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.

Use TASM calling convention syntax for previously identified ZUN functions With TH03 changing the calling convention for most of the code from __cdecl to __pascal, I've been getting more and more confused about this myself. So, let's settle on the following consistent syntax for function calls: * C where the calling convention is actually __cdecl and where TASM's emitted __cdecl code matches the original binary * PASCAL where the calling convention is actually __pascal * STDCALL where the calling convention is actually __cdecl, but where the caller either defers stack cleanup (summing up the stack size of multiple functions, then cleaning it all in a single "add sp" instruction) or where the stack is cleared in a different way (e.g. "pop cx"). Unfortunately though, when using the ARG directive to automatically generate an appropriate RET instruction for the given calling convention, TASM always emits ENTER and LEAVE instructions even when no local variables are declared, which greatly limits the number of functions where we can use that syntax. -.-

Use TASM calling convention syntax for previously identified ZUN functions With TH03 changing the calling convention for most of the code from __cdecl to __pascal, I've been getting more and more confused about this myself. So, let's settle on the following consistent syntax for function calls: * C where the calling convention is actually __cdecl and where TASM's emitted __cdecl code matches the original binary * PASCAL where the calling convention is actually __pascal * STDCALL where the calling convention is actually __cdecl, but where the caller either defers stack cleanup (summing up the stack size of multiple functions, then cleaning it all in a single "add sp" instruction) or where the stack is cleared in a different way (e.g. "pop cx"). Unfortunately though, when using the ARG directive to automatically generate an appropriate RET instruction for the given calling convention, TASM always emits ENTER and LEAVE instructions even when no local variables are declared, which greatly limits the number of functions where we can use that syntax. -.-

Use TASM calling convention syntax for previously identified ZUN functions With TH03 changing the calling convention for most of the code from __cdecl to __pascal, I've been getting more and more confused about this myself. So, let's settle on the following consistent syntax for function calls: * C where the calling convention is actually __cdecl and where TASM's emitted __cdecl code matches the original binary * PASCAL where the calling convention is actually __pascal * STDCALL where the calling convention is actually __cdecl, but where the caller either defers stack cleanup (summing up the stack size of multiple functions, then cleaning it all in a single "add sp" instruction) or where the stack is cleared in a different way (e.g. "pop cx"). Unfortunately though, when using the ARG directive to automatically generate an appropriate RET instruction for the given calling convention, TASM always emits ENTER and LEAVE instructions even when no local variables are declared, which greatly limits the number of functions where we can use that syntax. -.-

How do you even get a compiler to do this (and no, I haven't found a compiler switch)? No way around writing a separate "optimizer" as part of the compilation pipeline, it seems.

Use TASM calling convention syntax for previously identified ZUN functions With TH03 changing the calling convention for most of the code from __cdecl to __pascal, I've been getting more and more confused about this myself. So, let's settle on the following consistent syntax for function calls: * C where the calling convention is actually __cdecl and where TASM's emitted __cdecl code matches the original binary * PASCAL where the calling convention is actually __pascal * STDCALL where the calling convention is actually __cdecl, but where the caller either defers stack cleanup (summing up the stack size of multiple functions, then cleaning it all in a single "add sp" instruction) or where the stack is cleared in a different way (e.g. "pop cx"). Unfortunately though, when using the ARG directive to automatically generate an appropriate RET instruction for the given calling convention, TASM always emits ENTER and LEAVE instructions even when no local variables are declared, which greatly limits the number of functions where we can use that syntax. -.-

So yeah, there's indeed nothing wrong with piread.cpp. TH03 just uses that separate function that only blits every second row of an image, and indeed always loads the entire image as it would appear in a PNG conversion. Here's what happens if you display these images using the non-interlacing function: https://www.dropbox.com/s/885krj09d9l0890/th03%20PI%20no%20interlace.png

Use TASM calling convention syntax for previously identified ZUN functions With TH03 changing the calling convention for most of the code from __cdecl to __pascal, I've been getting more and more confused about this myself. So, let's settle on the following consistent syntax for function calls: * C where the calling convention is actually __cdecl and where TASM's emitted __cdecl code matches the original binary * PASCAL where the calling convention is actually __pascal * STDCALL where the calling convention is actually __cdecl, but where the caller either defers stack cleanup (summing up the stack size of multiple functions, then cleaning it all in a single "add sp" instruction) or where the stack is cleared in a different way (e.g. "pop cx"). Unfortunately though, when using the ARG directive to automatically generate an appropriate RET instruction for the given calling convention, TASM always emits ENTER and LEAVE instructions even when no local variables are declared, which greatly limits the number of functions where we can use that syntax. -.-

So yeah, there's indeed nothing wrong with piread.cpp. TH03 just uses that separate function that only blits every second row of an image, and indeed always loads the entire image as it would appear in a PNG conversion. Here's what happens if you display these images using the non-interlacing function: https://www.dropbox.com/s/885krj09d9l0890/th03%20PI%20no%20interlace.png

Use TASM calling convention syntax for previously identified ZUN functions With TH03 changing the calling convention for most of the code from __cdecl to __pascal, I've been getting more and more confused about this myself. So, let's settle on the following consistent syntax for function calls: * C where the calling convention is actually __cdecl and where TASM's emitted __cdecl code matches the original binary * PASCAL where the calling convention is actually __pascal * STDCALL where the calling convention is actually __cdecl, but where the caller either defers stack cleanup (summing up the stack size of multiple functions, then cleaning it all in a single "add sp" instruction) or where the stack is cleared in a different way (e.g. "pop cx"). Unfortunately though, when using the ARG directive to automatically generate an appropriate RET instruction for the given calling convention, TASM always emits ENTER and LEAVE instructions even when no local variables are declared, which greatly limits the number of functions where we can use that syntax. -.-

[Reverse-engineering] Slot-based PI display Also covering the two variations for blitting only every second row or blitting only a 320x200 quarter, as seen in the endings. So yeah, there's indeed nothing wrong with piread.cpp. TH03 just uses that separate function that only blits every second row of an image, and indeed always loads the entire image as it would appear in a PNG conversion. Here's what happens if you display these images using the non-interlacing function: https://www.dropbox.com/s/885krj09d9l0890/th03%20PI%20no%20interlace.png

[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] Slot-based PI display Also covering the two variations for blitting only every second row or blitting only a 320x200 quarter, as seen in the endings. So yeah, there's indeed nothing wrong with piread.cpp. TH03 just uses that separate function that only blits every second row of an image, and indeed always loads the entire image as it would appear in a PNG conversion.

[Reduction] Separate functions for 1D and 2D vector construction Look at that TH05 vector2_at_opt function. What the hell, the caller is supposed to set up the stack frame for the function?

[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.

Clean up the last remaining misanalyzed procedure boundaries After spending a few hours on correctly decompiling ZUN's bulky custom text renderer used in TH02 and TH03, it unfortunately turned out that TLINK doesn't actually give us the fine-grained control over segment ordering we'd like to have in a project like this, and that we can't slot code from one object file in between segments from another object file. This means that yes, we really have to decompile the functions in the order they appear in the executables, starting on either end. So, have a boring janitorial commit instead.

[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.

Identify all function pointers referenced from code > introduce a new macro to halve the lines of a far function pointer assignment, hoping that this commit will end up deleting more lines than it adds, because TH03 has lots of those > oh wait, these games mainly use near function pointers > unearth even more new functions in the process Seriously, how many more functions are still hidden in this codebase? And all that just because IDA was not smart enough to begin with.

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.
