If you can't figure this one out I won't be able to help. (Click on the sign to choose the type of conversion, then input your number/binary string). The decimal -> binary can take a couple of seconds. There's no delay but scratch is slow occasionally :D
I was bored one day. Idk if there are other programs like this but none of it was copied of other projects. It was actually made in offline editor when I was bored one day so you'd think it would be quite hard to copy so
