I'm aware it doesn't work with modern Scratch, but apparently emulations of older versions still work with it.

I found my old Picoboard recently. Way back when, my aunt accidentally knocked it off of my desk and it hit the tile floor. I don't see anything wrong with it physically, but it stopped working entirely after that drop. Does anybody have experience with this sort of thing and know what might be wrong, and if it's salvageable? I'm potentially learning how to solder at some point as well.

Google it. Someone probably has some sorta YT video about it.
I think Pico is mad at you now lol
