Hello. I recently got into wondering how to run my own code on the PSP. With a bunch of articles I found that explained how to find potential flaws within a PSP game, I finally found a game which became useful for this. This exploit is called Srabblehax. Scrabblehax is just a simple stack smash exploit for the game Scrabble on the PSP. It allows unsigned code execution to run on the PSP.

As of now, the exploit itself only runs a very simple payload which would flash 4 different colors on the screen. I'm currently working on improving my binary-loader (as it's broken as we speak). But I'll make improvements over time.

Anyway, feel free to try this out. I was only doing this to learn about PSP exploitation and this seemed to be easy to do too. Credits to Wololo and qwikrazor87 since they helped me out get started with this. Enjoy and feel free to ask questions :D

Dude! Awesome job! I love when new exploits are discovered on old consoles. Good job! :)

well i never thought i see another new exploit on the psp. great job
I actually have another coming up x)

EDIT: And I just updated the binaries since the original payload was unaligned by 3 bytes. So, it's working again and there won't be any random crashes during the payload is running.

    @Xdqwerty there is health behaviour you can add to your character, then to use a health bar is lil more complicated, google n watch a few tutorial video on it, be too hard to explain here.
  • Xdqwerty @ Xdqwerty:
    @BigOnYa, the character has the health behavior
  • BigOnYa @ BigOnYa:
    I know you have to create a health and health max variable. Then there is a calculation you use in code to subtract width size of the health bar. Google few vids.
  • Xdqwerty @ Xdqwerty:
    @BigOnYa, the "greenflatbar" is one of the preset health bars btw
  • BigOnYa @ BigOnYa:
    Yea you can use any bar/sprite. It will just change the width. Ok good luck and have fun. I'm off to go shoot some pool at the bar. Talk to you later.

  • Xdqwerty @ Xdqwerty:
    @BigOnYa, why does the health behavior exist if you can just use a variable?
  • Xdqwerty @ Xdqwerty:
