@Cyan - Thank you. I haven't installed anything yet, but I've read a lot the last few days. One thing I did't get: I it really "wise" to install something with a "fake" ticket? I mean, if a emunand get's released, wouldn't it be better to keep your NAND "clean" before you dump it the first time?
I read somewhere that the "fake-tickets" are stored within the NAND.
it's always better to keep your real system clean.
any launched/installed title or even just inserted disc install its ticket and the system keeps it.
disc tickets are probably stored in a specific folder, and eshop tickets in another one.
so by doing this method, it's installing this ticket in the eshop folder, and you can have different tickets for the same game (one disc, one eshop).
What's bad is that if you try to buy the official eshop game later, it might detect you already have a ticket for that game and refuse to acknowledge the transaction ? or it will replace it, I don't know.
Also, the eShop ticket you now have doesn't contain the consoleID and is not tied to any console (but the HDD is per-console encrypted, you can't transfer or play on another console without re-installing it).
It's unknown if Nintendo can detect this. It would require : upload of the ticket or part of its data to verify it at launch (unlikely that it's already doing it, as it works offline), or update the wiiu to add this function (users won't update).
Know that we can dump tickets from eshop games, we should compare them.
eshop will obviously have the tied ConsoleID in it. but I don't know what else will be different.
