I love the pin level emulation model of this. The self contained modular behaviour of components has real flexibility.
For a long time I have wondered if extremely thin but explicitly defined interfaces are an under-explored domain for interoperability.
Beyond simple chip emulation, any set of values that are sampled on each side of the interface at defined times, and a small set of signals to provided temporal access. Be it pins, a small set of registers, or a memory mapped region, it seems like an excellent target for conformance testing.
Perhaps in a world of AI generated code, modular components with explicit conformance requirements would allow people to not care what happens inside the black box, provided it cannot be made to violate it's behaviour requirements.
I don't know about anyone else, but this really reminds me of 0x10c [0]
I'm still fascinated by the idea of a setting with virtual mini computers, I've designed a couple as thought exercises based on it/space travel as well as cyberpunk mixing in a little Zach like flavour for some of the chip design, even figured out a fantasy variant
Not sure why, but I've not been able to convince myself that it's anything other than ultra niche, so if you're interested in this and want to talk about it, chime in here or drop me an email (in profile)
Apart from the 'pin-emulation' the other interesting feature is that the CPUs are 'cycle stepped', e.g. the CPU no longer has a special 'controller role' in the system but is just 'ticked along' with all the other chips. This blog post describes how that works for the Z80 emulation (the instruction decoder is still a big switch-case, but with one case-prong per instruction cycle instead one prong per whole instruction: https://floooh.github.io/2021/12/17/cycle-stepped-z80.html)
I didn't really get around to work on the project since 2023 though (and before that I worked on it mainly as a 'vacation project' over the Christmas breaks), I mostly just updated the sokol and Dear ImGui dependencies since then, and sometimes added new scene demos appearing on https://www.pouet.net/ and https://csdb.dk/.
Thank you for demonstrating how great and underrated the Amstrad CPC is (and the comparatively undeserved strength of the British nostalgia distortion field towards the ZX Spectrum ;) )

Bruce Lee on ZX spectrum was my jam!
where'd you get this preview one from OP? linked somewhere?
