Hi all!
I found a ZX80.rbf core browsing Gehstock's github repository:
https://github.com/Gehstock/Mist_Cores/ ... air%20ZX80
Tried it on my MiST using differet monitors, but the result was no picture in every setup (15/31kHz).
Is it a work-in-progress core, or am I missing something?
Unfortunately there's no readme/howto documentation, perhaps the core needs an external .rom file?
Attached my results from the TV's framebuffer:
