I noticed that the visual6502 python implementation has been used to build an Atari simulation - https://github.com/gregjames/Sim2600.

It's awesome but painfully slow. Has anyone made a similar Atari simulation with the perfect6502 simulation (written in C instead of python)? (https://github.com/mist64/perfect6502)

It seems like perhaps the main tasks would be to implement the TIA and a way of rendering the pixels. The Sim2600 python repo has an implementation of the TIA already, so I guess this would just be a port.

Thanks for any pointers you might have,

Dan

Honest question: how would this be better than, say, Stella?

This is for a research project where it's important to have all the transistor values.

Previously this was published: https://journals.plos.org/ploscompbiol/ ... bi.1005268

I want to try some similar experiments. In the paper they say they used a C++ version, but the code looks like Python / Cython to me (https://github.com/ericmjonas/Sim2600). It runs at like 1 KHz, whereas the perfect6502 sim runs at closer to 50kHz. Still not fast, but I can do a lot more experiments that way. With the 1kHz version, it takes literally hours to render enough frames of the game for anything interesting to happen on the screen.
