dw2003recomp v0.4.0

The launcher, the PC port and its mods, for Linux and for Windows.
Bring your own disc image of Digimon World 2003 (PS1, Europe; the launcher checks its SHA-1).

Linux x86_64: dw2003-*-x86_64.AppImage: chmod +x it, then run it. Needs glibc 2.39 or newer (Ubuntu 24.04, Fedora 40, Debian 13 or later).
Windows x86_64: dw2003-*-windows-x86_64.zip: unzip, run dw2003-launcher.exe (unsigned: SmartScreen's "More info", "Run anyway"). Windows 10 or newer. Tested on Linux under Wine and Proton only, not yet on real Windows: reports are welcome in the issues (#37).
The .debug file and the -symbols.zip are the programs' debug info for crash reports (not needed to play).

Full Changelog: v0.1-matching-closed...v0.1.0

v0.1 — matching milestone

The matching milestone, as first published.

• 98.6% of game code compiled from matching C (3,598 / 3,606 functions): the EXE and all 293 WSTAG stage overlays at 100%, the 19 tier-1 overlays at 98.1%, the tier-2 battle overlays at 95.7%. The 8 holdouts stay as split assembly.
• Every game file rebuilds byte-identical (scripts/build.sh --check: 2,100 outputs, SHA-1 verified).
• Reference tests (scripts/test.sh): goldens of the game's logic generated in the emulator and replayed on the host, record/replay scripts, and format checks.

No game data is included: building needs your own disc of the EU release (SLES-03936). No binaries attached.
