Well, as I said, option one isn't the real thing, and I replaced it with something most people here could understand
Otherwise, I can just put the whole true story here, it's just going to be long to read for you.
So, for quite some time now, I've been using pirating tools on my 3DS XL, but pirating nothing. I basically only use those tools for homebrews and other openness-related things that have nothing to do with piracy. You may think this is stupid, and yes it is, especially considering that this tool is really convenient to use for pirates, but really (read: REALLY) annoying to use for people like me. That's why I considered switching to a new hack that is now out and stable, and that suits my needs a lot better (a lot less pirate oriented but I don't care, and a lot (read: A LOT) more convenient to use).
The problem is that due to Nintendo trying to stop pirates, if I switch to that less pirate-oriented hack, I can't use any savegame I have got now. Yes, you read right, by trying to stop pirates, they also prevent people from leaving the pirates they never liked. And yeah, I only care about MH4U, the other games don't matter as much.
So the real choice is :
1) Keep using that stupid first hack even though I know that I can use something that is a lot better (and that actually works, I tried it)
2) Use the new one but lose my MH4U savegame
And actually, the real problem about MH4U isn't really getting the items. It's really easy nowadays to get anything you want without even farming. So basically I could just do that...
But that's not the spirit. I'd like to keep my 500 hours and be able to say "I got my armors by farming them" instead of saying "well, I had armors I deserved but due to not being a pirate, I had to use hacks to get them back, flawless logic".
Or yeah, I guess I could start over for real and get everything back after 500 new hours but that would be very annoying...
