Backstory #

I first got Celeste actually...according to Itch.io, 99 days ago from the writing of the post. I ended up starting the game on my school's Spring break so I had plenty of time to figure out the game. Like everyone I was somewhat amazed by the game and how fun and frustrating it was at the same time. So I thought, "hey I'd be nice if I could play this in school if I needed to". Unfortunately I actually got the project to a playable amount only one day after school ended.

First Attempts #

So I managed to google around, to this helpful gist by TheSpydog. After reading some documentation on the Everest modlaoder I managed to use ILSpy to decompile the game. For a while I was actually not able to figure out how to get a meaningful stack trace in the browser so I was very unmotivated for the time being. I ended up writing an Everest to get a feel of how everything works and coming back to it later.

Overview #

The process pretty much was like this

1. Compile game for web (8 to 11 minutes normally, 5 minutes in Interperter mode)
2. Wait for game to load (1 minute without a lot of optimizations, approx 15 seconds with optimizations)
3. Trace errors, in non-interperter mode you don't always get nice stack traces. Interperter mode works until FNA initalizes it's screen due to a Pinvoke signature bug.
4. Repeat above

• Next Up: Install (WIP)
• Previously: Dev Environment
