The 3DS browser exploit allows running unsigned code with no 3rd party hardware

[0xFFF1]

So far it has been used to allow for 6th gen Pokegenning over on Pokemon XYORAS. How about we use this same exploit to unlock all custom moves for Smash Bros 3DS, which in turn allows anyone to get any custom moveset on their Smash Bros Wii U. This means we can easily allow all custom movesets for Smash Wii U tournaments without someone having to grind out every custom move on every Wii U they are using for their tournament. I mean if this is still a problem.

Or you could just buy a Powersaves 3DS Pro.

This allows tournaments to lower the cost of unlocking customs. No need for them to buy a PowerSave, just a 2DS.
