besides the fact that it was written in rust, rust happens to be a really nice language to write emulators, you don't have to think much about threading and not much abut memory management, rust makes that easy => you can concentrate on your pixels. Moreover LLM grasp it very well so that you can get a bit more spare time for your emulator-side-project.

It was very long since I wrote any sort of C++ and using rust was pretty refreshing.

Second "besides": marty's PC may not have a lot of breadth in terms of supported hardware, but it gets the accuracy totally right. It's a very special kind of achievement.

(I'm not a rust fanboy :-) I just appreciate the language for writing my emulator)
