Use your mouse, Drag downloaded files (the en_152.swf file) into the Autoresponder tab in fiddler
It should look like this. Make sure "Enable auto.." and "Permit pass..." are both ticked.
Clear browser cache.
Enter Ninja Saga
Go to the hunting house and fight the Gingerbread hero. 1 hit and he should be dead, else you did not replace the .swf file properly. Remember to clear browser cache!
Select all 3 files and drag them all into the Autoresponder tab of Fiddler.
Make sure 'Enable auto...' and 'Permit passthrough...' are both ticked.
Enter Ninja Saga. If you are using firefox, make sure Fiddler mode is ForceOn. (Check the Tool's Tutorial above if first time using fiddler)
If all 3 files are replaced correctly, visit the SHOP in Ninja Saga and go to Items.
You should see 3 items. Reset, 50M and Invite GODKNOWS team.
Just select the cheat you want. If you want to have both Ryuzaki and MissDex to fight for you, select GODKNOWS team. They are both level 100. Have fun.
