No Problem when You mean
But ive right and anyone find a way in the future to Crack a Preview Version from oddesey ...
Normal homebrew like emulators and things like that are a real possibility for the switch sometime soon like within a year (maybe longer/shorter) and even "back up" loaders for games that require 3.0 or less could come around at some point depending on if devs want to deal with the whole piracy thing or not. Games that require 3.0.1 or more most likely will not be able to be played on a "back up" loader and if they can it will probably be years away. Hard modding also doesn't really look possible because of how tightly the hardware is packed into the switch. For general homebrew, once the switch is hacked it will be an amazing emulator machine and probably other clever applications that the devs can come up with. So if you like the sound of that and you don't mind missing out on all the games from 3.0.1 onwards for possibly years and years then staying on the lowest firmware you can is a good idea. For everyone else it is just best to update and enjoy the games.
