Yes but why would you charge for something that is free by other means necessary. Its wrong to charge unless you need to pay for a KV but thats JTAG wise.
A jtag isn't necessary and these things can be done for free and with a usb. If you haven't looked there are various threads for USB Mod Menus that do most of the things you said.
Exactly I was a USB modder for some time. then i moved to ISO mods for now untill i buy another JTAG. I would know. Default.xex cant run Physics n flex v2 on JTAG only ISO. If you guys dont want to pay this guy for something that is free just message me on xbox. ill hook you up. GT: HTC x Android
Yes its very fair no one needs to pay you for something thats free. If your using a JTAG on say MW3 i understand but your not, Its W@W not mw3 i would know what needs payed for and what doesnt. I have a Falcon JTAG and i pay for KV's for certain games. But to reduce the amount of bans that happens I stick with ISO mods.
