As I don't have any new project in the pipe, I spent my saturday going back to see if I have progressed in #6502 #assembly, and gave a bit of attention to my #Quicktake for #Apple2 JPEG decoder.
I think I progressed: decoding a Quicktake 200 photo now /only/ takes 190 seconds (3 minutes 10), a 25% improvement and a whole minute less than previously!
