I have crazy weapons in MH4U, crazy equipment and talisman; that's why I'm making the question. The problem is I don't know how to edit in "Hex Editing". Im very slow with that kind of things.
The thing is, it can't be done just by save editing, I'll explain, in MH4U, there were relics that had certain absurd values, due to how they were coded, however, those absurd values were just a result of how all other values were calculated, and remained unused. With the Save Editor you were able to get equipment with those crazy amounts of power, you just had to "tap into them", in Generations however, you can't because all weapons have a fixed value, in other words, you can't tap into crazy power because there isn't any already there coded. I may be wrong, but I'm pretty sure Generation's weapons all have fixed values, unlike relics in 4U which kinda acted like a blank check, dunno if it they can be changed with Hex editing.
Luckily there is an alternative, albeit a little more complex, using NTR cheats you can get crazy whatever, even more than the Save editor is able to do, however, it's a little bit more complicated to use, nothing crazy complicated, but just a little tiny bit more complicated, I encourage to look into those, any help I can provide, you can PM me and I'll gladly help you out.
