“Hacking” highscores

I’m looking for a little program that will allow me to edit highscores. So, when I finish a game, and click: Send highscore, I can change the highscore to 99999999999999 for example.
Anyone has any ideas? It has to work with the games on funnygames.nl
Answer #1
Hacking Flash High Scores
First you need to be running Firefox and you need to get the extension tamper data. You can get it here: https://addons.mozilla.org/en-US/firefox/addon/966

Tamper data is a plugin “to view and modify HTTP/HTTPS headers and post parameters.”
Once you have the plugin find a game you want the high score in. I will be using this simple pac man game. http://www.thepcmanwebsite.com/media/pacman_flash/
You will want to start by immediately losing, as weird as that sounds, but trust me. After you lose it it will ask you to enter your name for the high score. This is when you want to go to tools > tamper data and have it running.

Then click “Start Tamper”.

Go back to the Pac Man window enter whatever name you would like and click “OK”. immediately Tamper Data should pop up with something looking like this.

You are going to click Tamper. You should see all of the post parameters you can change on the right. In our case we are going all the way to the right of the text in the POST_DATA parameter where it says score=XXXX. Change this value to whatever you wish, but the highest value on this particular game is 999,999, then “OK’ at the bottom.
Walaa!¡!¡!¡ The high scores should load with your name at the top (or near the top, since I’ve done it on this game several times ).

Answer #2
Yeah, I already have tamper data, but when I try it at www.funnygames.nl it doesn’t work, somehow…
When I START TAMPER, I only get this POST_DATA on the right of the screen:
game%5Fchk=3e791762b90b4eb4df7f88fe74318c9c&game=3062%5F2871&session=2a7b32bf232368160e5bfcd17b19b175&score=175&length=3
It seems simple enough, just edit the score variable and alter the corresponding length variable, but when I do that is says:
” Are you sure you want to Change the Content-Lenght Header? ”
I’ve clicked both OK and Cancel, it just gives me “Flash POST Data incorrect (4)” on the webpage itself…
Any ideas?
Answer #3
give me a link to the game you were playing and I will try to help
*sometimes tamper data doesn’t work for all games*

Just replace the 0 with an o.
EDIT: And check these highscores… I think it is possible to cheat here.
