P2000 appears to be at least partially emulated in MAME: https://emulation.gametechwiki.com/index.php/Philips_P2000_e...

Here's a video of it running: https://www.youtube.com/watch?v=PUa9Ktmsxww

The ROM seems to be available via the usual unofficial sources for MAME-supported ROMS: https://wowroms.com/en/roms/mame/download-philips-p2000t/974...

I'd suggest leveraging the MAME distribution model (distributing emulators separately from copyrighted ROMS). You could also contribute the abandonware software titles you've preserved to the MAME Software-List: https://docs.mamedev.org/contributing/softlist.html. There's no sense in re-inventing the processes and standards the preservation community has already established. Plus once you start the ball rolling, the active community of people trying to preserve cassette-based software from niche 8-bit platforms can join in.

Of course, getting ROM distribution officially blessed by the corporate owner of record would be lovely but it rarely happens because of the legal complexities involved. Obviously, there's zero commercial value anymore but it's still much easier for a corporation to tacitly look the other way than to grant express permission.
