cdirecomp, very early research that recompiles the whole Philips CD-i system ROM as native code.
cdirecomp is a static recompiler ecosystem for Philips CD-i games, translating SCC68070 machine code (a 68000-family CPU) into C. Its distinctive choice is scope: it recompiles the entire CD-RTOS/OS-9 system ROM rather than writing a hand-made OS-9 high-level emulation layer. The project calls itself "a research project shared in the open, not a finished product".
What works today
In the project's own words, it is in "Very early development" and "boots the real Philips CD-i system ROM as native code and can perform a very basic boot of a CD-i title. Hotel Mario reaches its title card. Gameplay is not yet reachable". A clean-room interpreter is kept as the correctness floor beneath the recompiled code.
Enhancements
None yet. The work so far is entirely about correct boot and system-ROM execution.
Known limitations
No game reaches gameplay. Hotel Mario stops at its title card, and there is no compatibility story beyond that basic boot.
Software
No game pages exist for this platform yet.
Reading
cdirecomp ships no BIOS ROM, no disc images, and no game-derived generated code; the user supplies their own system ROM and Mode-2 cue/bin dumps.
