Anyone fancy trying this?
ONLY PEOPLE WITH VOL+ STRAP FITTED NEED APPLY!
This UF2 (going to be 0.9.7 once finished) has a new feature.
Hold vol+ for 5 seconds, you SHOULD see a rapid confirm LED flash and the chip will start blinking out payload numbers...
1 blink = payload 1
2 blinks = payload 2
etc
Press vol+ again to store, chip reboots and launches your selected payload and if you reboot simple-uf2, it will show the currently selected payload on the screen.
Someone give it a try pretty please.
