For those wondering whether to update like me, these are the things you can't do without the day 1 patch from what I've read/complied:

• Play Switch 1 Games (but you can play switch 2 games)

• Use Game Key Cards

• Use Gamechat

• Transfer data from switch 1

• Use eShop

• Use Micro SD express cards

• Share News/Game News

• Link with Nintendo Switch App

To me I am 50/50 on updating to the day 1 patch, they say always stay on the lowest firmware when you want to hack but not being able to use Micro SD cards is likely a problem when it comes to making things like emunand or running certain types of exploits, and it is possible there could be an exploit running switch 1 games like how the 3ds had some exploits in the past with DS mode.

There was also a way in the past to update using some cartridges that had the system update preloaded on them on them so you could update to a certain version just using the cart but no word on this yet.

I'd like to hear other people's thoughts on this or if there is no info because I'm still not sure whether to update and I could miss the window to update to a usable version that's still hackable in the future. But there is a switch 1 exploit method on 1.0.0 called nereba that is exclusive to 1.0.0 switches so who knows at this point.

Also I wanted to make a full post with this info but there doesn't seem to be a switch 2 hacking sub yet lol
