Oh man I loved my PSP back in the day, I played a ton in it. I had a modded one and I also installed PSX and GBA emulators.

I remember that when I bought it, it came already modded but it wasn’t a permanent mod. To activate the mod after rebooting I had to navigate to the images folder and load up a PNG (I think?) image that was called Chicken or something like that. The most annoying part was that it didn’t work consistently, so often times it would cause the console to hang and I had to try again. It always blew my mind how an image could trigger the hack like that, looking back I guess it was a malicious payload or something and some race condition somewhere idk.

If I remember correctly, after a couple years I was able to change the mod to a permanent one. I sold it like 10 years ago
