A lot of people say they enter codes to see the flame? Where can I find that?

Go to yours toribash folder >>custom>>player and inside that folder like for example Uke. There is file called "item.dat" open it with notepad and there you will find FLAME 0;0 0 0 0.....
so just edit this part FLAME 0;"0 0 0 00 0 0 0 0 0 0" for example FLAME 0;"0 3 0 54 0 11 0 0 0 4 0" there you go you have nice flame developed by you. ;)

Thank you!

Or you could do it the easy way...

In-game>Options>Utils>Flame Browser> Enter number in whatever box...
