“Not Used” is button 1024, and was [START] in SmileBASIC v2.x (Petit Computer).

Actually, the start button isn't 1024. It's 70?? and you can hold it down when starting programs to use it.

No, start and select are both 8192. 70 is when you're pressing X, down, and left.

button 1024 is actually unused. there can't be a button 70 because BUTTON() returns a bitset

I’m not saying that is is used, I’m saying it →→WAS←← used for start in Petit Computer.

“It is”, not “is is”.

I didn't mean "70", I meant somewhere around the 7000s. That was what the Xs were for. (whoops, it was more around 8000s...)

yes, button 8192. powers of two, my man :P
