@kometbomb there was effort early on with help of @zep to get the sound generation close. what differences are you hearing?

What's the current state of this? Which fork is to be used?

gamax92's fork seems the most active right now.
It also fixed del behaving differently (delete all occurrences instead of the 1st one as in pico8), which apparently also fixed the "del in foreach" crash mentioned in the first post (that said, you should avoid modifying your sequences during an iteration, esp. removing an element in a forward iteration!).

For now I'm on vanilla PICO-8 but I'll have a further look at it when I need to port my game. Or when I'm fed up with simulating pico8 original functions myself to run my external lua unit tests.
