Yahoo!!! I've converted the codes and added a couple of extras too!
I hope you all like it and TRY hacking you own.(I'll put 'em up here for ya, and give YOU the credit.)
In the end of each code entry there is an M or a NO.This indicates who made the code.
LEGEND:

M=These codes were made and converted by me.

NO=These codes were NOT made by me, but were converted by me.
