Awesome to see 😎

Oh let me know if I can help with Switch testing

[hippydave]

Thanks for that, the input seems to be working fine. I noticed for the one cart I tried, the cart data was saved, but not reloaded.

[jtothebell]

Which cart was it? I found one bug today that could have prevented some data from saving.

[hippydave]

It was actually my own old game, Cellephant https://www.lexaloffle.com/bbs/?tid=29736

Oh, thanks. That turns out to be a separate issue. The Pico-8 wiki doesn't mention cartdata returning a boolean, but the manual does. I wasn't returning anything, so in Cellephant the check if cartdata("bittwist_cellephant") would always be falsy. Just pushed a fix if you want to try it (you can also download the artifact of the latest action):

That fixed it, good job!
