@TheMogMiner I read what you wrote about CD-i emulation and the difficulties faced; but my eye as drawn to you mentioning no dump for certain variants, etc. Are you sourcing them/trying to get them decapped or can the DU/me chip in cash or something?

Replying to my own post, and in the hopes that
@Interact_Dreams sees - the CD-i platform rather interesting, and has unique hurdles to emulating it. Dumping the systems involved and ensuring good community coverage is only part of it, but it's a good start.
One of the most interesting things to me is that the CD-i platform was more akin to platforms from around 2005 onward than its late-80's contemporaries. It was the first console that demanded developers interface with just the system libraries, and avoid direct hardware access.

It's worth mentioning that this presents multiple issues for emulating the CD-i: It's not a matter of emulating a single platform, it's a matter of emulating a specific implementation of the player spec.

Some players are straightforward enough: A Philips SCC68070 (68k-derivative SoC), a Motorola DSP56k for audio, a Motorola 68HC05 for I/O, and another for CD servo control. Some have the latter three components all rolled into one ASIC (IKAT).
