th01/zunsoft: Initial state Yup. th01 *is* different from any other game, and that includes the initialization program. It neither consists of three smaller programs smashed together, nor does it seem to have any output.

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 Also, we're finally defining the Borland C++ model symbols directly in the code, rather than in my unpublished build batch files.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. [Binary change] Relocations in TH01's REIIDEN.EXE, again.

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 "Abnormal program termination" to its own slice That was the very first function reduced, before I came up with the data slice model in 59688e23fc5ff0d252b92c2ef40e486098dd3eac.

General cleanup Mostly moving spurious null bytes, which are actually supposed to denote alignment, into their associated slices, but also prettying up some of the very first slices.

[Reduction] #225: Clipping variables for drawing Well, great. Why did the trapezoid variables have to be included in this object file? 10 of the executables don't use them, and there's no way to locate that one needle in the haystack of uninitialized data now.

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. :)

th01/zunsoft: Initial state Yup. th01 *is* different from any other game, and that includes the initialization program. It neither consists of three smaller programs smashed together, nor does it seem to have any output.

Change the name of the entry point to STARTX Because it just so happens that master.lib's bfnt_header structure contains an element named "START". And huh, this suddenly works without changing any assembler or linker parameters? I swear it didn't when I tried it first.
