I've just been made aware of THIS
Looks like a work of love. I've tried out the Windows VST3 version and on my i9 under Cubase it's working nicely, though I'm getting glitches on certain patches, which must be more demanding of the emulator.
This kind of emulation is something of an interest of mine. I have a few devices (Raspberry Pi, Amazon Firestick, handhelds) that emulate some of my favourite old gaming machines (especially my beloved Commodore 64). It's interesting, and gratifying, to see that there is interest out there for emulating specific low-level devices to do such as this.
