Is the version I'm at now. I wanna play mario maker but I'd have to update to go online so I'm checking here before screwing it up, hopefully this will be useful to others too. Please answer these if you can. 1) what is the difference between 5.3 and 5.4 and why can't the latter run any hacks? 2) what is the difference between 5.4 and 5.5 and why have I been advised not to update? 3) are there any unreleased hacks that would make 5.3 and 5.4 essentially equal and have the developers any plans on releasing them? 4) same as previous but for 5.5. 5) is 5.4 ever getting a firmware spoofer? 6) why isn't there a homebrew launcher? I mostly want homebrew and this is pretty inconvenient. I will retribute your kindness by being a good boy and support developers when I'm able to visit eShop.
