alot of flash games are weak when it comes to submitting scores, yes, you wont be able to hack popular sites like pogo or neopets, but 95% of flash games you will now own.
firfox has a built in packet editor in their browser, its called tamper data, this is how you use it to get highscores on flash games.
step 1
DOWNLOAD FIREFOX(safe)
----------------------------------------------------------------------------------------
step 2
install the official necessary hacking plug-in called
Tamper Data by going on mozilla firefox and clicking
THE OFFICIAL FIREFOX ADD-ONs PAGE and typing "tamper data" in search and downloading that add-on.

step 4
enter your name and score something high enough that will allow you to submit your score, but DO NOT SUBMIT YET.
----------------------------------------------------------------------------------------
step 5
this is where it gets a little tricky, go to "tools > Tamper Data" on the top of your mozilla firefox and click "start tamper"
----------------------------------------------------------------------------------------
step 6
remember what your score was and click "submit score" and you should get a pop up, click "tamper" and your looking for something that looks like
THIS PICTURE----------------------------------------------------------------------------------------
step 7
if you dident get a window that looks like that the first time then just click ok at bottom and another should pop up, press "tamper" untill you find a box that looks like the one in the picture above.
----------------------------------------------------------------------------------------
step 8
remember what your score was? look in that confusing code (Where i circled in picture) and look for your score in there, edit it to what you want and click ok.*NOTE* Dont edit anything but your numbers**
