Ok, if u get caught with this, you WILL get banned, its with ur own risk, what this hack does, is show you that u are riding a chocobo, making u as fast as if u are riding one, but other people will see u running, so be careful.....
In order to do this, you are going to need Tsearch, and a windower from
www.ffxi.archbell.com
open tsearch, press on target program, and select pol.exe, next press on search, and do the following:
Now, when you are sitting down, you will search for 33, and when u are standing you will search for 0.... on 4 bytes... keep repeating this untill there is 1 result left.... after that set it to 6(chocobo's value)... and VOILA, ur done
*Note* you will need to use the search next function in order to search from ur previous result....
