I'm looking it, but the code is not mine lol, have no idea how the guy got the addresses. This the code:
2F448B80 00FF01F4
It's basically change the amount of the item asociated to that slot in the inventary (MH3U). But couldn't apply, only with the browser method.
That alsoThe addresses change between the browser and homebrew launcher method. You can't carry over the codes without fixing them.
