What was done #
The repository tracks a numbered series of blockers while translating the PAL release of Devil May Cry. The title screen and an office cutscene run, but a first playable frame has not been shown.
This experimental project statically recompiles the PAL Europe release of Devil May Cry (SLES_503.58, version 1.02) for the PlayStation 2 to native PC code using PS2Recomp. The README calls it a reverse-engineering and bring-up effort, not a playable port, and lists progress as a series of named blockers.
Three are marked resolved: corrupted function boundaries at the entry point, a missing CD-read IOP service, and the movie streaming transport. A fourth, PSS movie data reaching the EE but producing no visible video, is still open in its tracking note. The author reports a real interactive boot, gamepad navigation of menus, and the title screen. After New Game the intro movie plays to the end and an office cutscene runs, with characters and most geometry now drawn after fixes to the VIF1 DMA chain walk, VU0 math helpers and a skinning-weight unpack mode. A streamed voice track plays through a reconstructed version of the game's sound driver, though not in sync.
Performance is very low, about 3 to 5 vertical syncs per second against 50 on PAL. The README says no first playable frame has been demonstrated. Commits carry Claude Sonnet 5 (20) and Claude Opus 5.5 (7) trailers.
