I'm curious how advanced the ZX Spectrum (and many others) core actually is. Assuming that ideally FPGA core should be a 1:1 representation of the original machine, how far are we from that ideal?
Of course I know it's probably impossible to measure in numbers, but any more in-depth detail would be welcome. Are there any milestones left, how accurate is ZX emulation, what's the compatibility, etc.
This question is partially inspired by comments made by the author of ZX Baremulator, on another forum. They partially refer to ZX-UNO, but the gist is that in general ZX Spectrum FPGA emulation is "far from perfect" (eg, contended memory, timings).

Re: The State of the Core: ZX Spectrum
I’m sure the purists will have complaints, but the current MiSTer core does everything I ever wanted it to do...
Re: The State of the Core: ZX Spectrum
slingshot updated ZX Spectrum core for the MiST to support snow effect and now ir contention works perfect, so the core is actually perfectly cycle accurate. https://github.com/mist-devel/mist-bina ... s/spectrum
