mildy related but wasn't there an emulator (maybe not GB but NES or SNES?) which had a visual panel showing each CPU cycle step by step? afaik it was very slow but the 1000% accuracy was the goal not playability.

My guess is you're thinking of no$gmb, a very early Game Boy emulator:

I've got fond memories of using this to get a preview of Pokemon Gold before it was released in NA!
Found it
MetalNES, transistor level NES emulation https://github.com/iaddis/metalnes
While searching I also found a new one, VisualNES https://kaiokendev.github.io/nes/about
There is also one for GB https://github.com/aappleby/MetroBoy
See also Higan, formerly BSNES, which among other things is a cycle-accurate emulation of the SNES hardware and its enhancement chips (like the SuperFX used in StarFox/StarWing):

I'm not sure if this is the one you are talking about but I remember seeing this a little while ago. https://mtmc.cs.montana.edu/
