Creating slingshot was a good idea, not only because having a custom launcher is awesome, but also because it gave me an excuse to jailbreak my playdate so I could test it on-device! I did this using Crank2Unlock, an app that shows your playdate unlock code. Apparently, through the serial interface, you can access a million commands hidden from the user until you use that code to reveal them, such as sysdisk
(share the system partition of your playdate's disk) and lcdtest
(shows a cool stripes pattern on the playdate).
HACKING STUFF IS SO FUNNNNNNNNNN!!!
