Hi Patrik, is there a CP/M version of these tests? If not, would you be interested in patches supporting that? Thanks.

The original https://github.com/trebonian/visual6502 code maintains separate states for nodes and transistors. 48a84a6a changed that to store transistors' states in their gate nodes, because these were always supposed to be the...

We currently only support handlers like `on_step()` and `on_read()`/`on_write()` that mandate the emulators to execute a single instruction or provide a mean to access a single memory cell. This prevents...

`scf/ccf` seems to be susceptible to the order nodes are getting updated in during simulation. Can be reproduced on https://github.com/kosarev/z80/commit/ec19a48df0cd9c022eeab8f8626e459090578b14, with seemingly any seed, though one time I observed all...
