Adding port Celeste

[DynaMight1124]

Hi

Started as a Sunday morning session, just wondering if AI could easily port it and actually went very well. Its the C port based on the original Pico8 game.

Works fine on ESP32, S3 and P4, has sound/music (needs to be on SD else the flash size was pretty big!) but works ok without it, just silent. Saves work fine too. Has two display modes, original Pico8 square aspect and a much wider aspect, you can choose which in the 'emulator options'

It was based on the great work here: https://github.com/valdanylchuk/ccleste

Awesome! I've always wanted to play Celeste on devices like these and tried (unsuccessfully) to get a Pico-8 emulator running.

This looks really cool. I wasn't aware there was a C port of Celeste.

I'll test this on my device ASAP.

It runs quite well since its a pure C port. Just make sure to copy the files to the SD card for sound/music. It actually come out quite nice, there was no sound engine and AI just magic'd one up, which worked! Quite amazing really, same for things like savestates.

I did also try Pico8, I/AI got fake-08 compiled and its mostly working, just not that fast, esp for Celeste, but other games run ok even if the fps are not super high. I added a branch for preservations sake here: https://github.com/DynaMight1124/retro-go/tree/pico8 I dont know if theres a way to get massive performance boosts without some pretty heavy optimisations.
