I fondly remember loading up a janky version of MAME that only ran Pac-Man via the newly discovered kxploit on my PSP in ~2005. That sent me down a two-decades-long road of fiddling with so many devices, making them my own.

I have huge respect for the folks who spent countless hours freeing devices like the PSP from the control of the corporations that wanted them locked down. I think we'll need a lot more of that spirit in the years ahead...
