Adding Stella

[DynaMight1124]

Hi

Been working on adding Atari 2600. Its a surprisingly 'heavy' system for something so old! Initially started off with an old Odroid port, which AI pretty much (amazingly too) got working within about 10 minutes.... but it wasnt very quick. Games tended to feel fine but the fps wasnt brilliant, the ESP32 was about 45-50 and forcing FS5. I wouldnt call it 'release worthy'

So I looked around and came across this port: https://github.com/wavemotion-dave/StellaDS for the Nintendo DS, clearly the dev had spent many years fine tuning it to run on a very underpowered DS with a lot of love and attention, felt like if anything could get 60fps on the ESP32, it could be this.

It kicked AI's butt for quite a few days, I gave up at least twice as it just wouldnt compile (it was trying to unpick some DS code) but second time I came back, it was only a few minutes from compiling, after that it was pretty solid. Spent some time getting all the features dialled in.

But yes it's been holding a solid 60fps on the original ESP32 with some to spare.

Heres a section of Space Invaders.
