pmdwinbuild

scripts to build pmdwin using MinGW-w64 with patches to fix some of the bugs

Binary diffs are now available: https://github.com/takamichih/pmdwinbuild/releases

For various reasons I didn't look at the pmdwin's source while reverse engineering pmd for 98fmplayer, but I decided to create patches to build pmdwin.

• Supports compiling under latest gcc (tested with i686-w64-mingw32-gcc 7.3.0 on Arch) instead of the ancient Visual C++ 6.0

  I think it is possible to build on Ubuntu, Ubuntu on WSL, or MSYS2 with minor tweaking (such as PREFIX variable in Makefile).

  However this might still contain some UB that would not manifestate under ancient compilers.

  Probably still compilable under MSVC and Visual C++ 6.0.

• Fixed some bugs:

  • SSG frequency error (0002-ssg-pitch.patch)

  • SSG effect bug (0003-ssg-effect.patch)

    Fixes noise sweep (Example: SSG effect #6: n6, which is triggered by SSG rhythm @64 "Snare Drum 2"

  • SSG relative volume saturation bug (0004-ssg-volrel-sat.patch)

    Fixes SSG relative volume change () ( commands), previously ignored instead of saturating if the change is too large

  • Linear interpolation bug (0005-linearint-fix.patch)

    Fixes off-by-one error in opnaw.cpp causing glitches when using "internally generate with 55466Hz" mode, aliasing caused by limitations of linear interpolator itself is not fixed

Because of licensing reasons (original license forbids redistribution of source and binary without permission) I only included the patches. The patches themselves are MIT license.

How to build

bash, wget, 7z, sha256sum, dos2unix, patch, Mingw-w64 i686 gcc is required. Makefile assumes i686-w64-mingw32-gcc for gcc.

1. git clone $this_repo
2. cd pmdwinbuild
3. make -j$whatever
4. pmdwin.dll is generated under build/ directory
