removable hbc would if an update ? wiikey

Link how to

okay so if i use this link and do what is says it should work on my wiikey v1 at 4.1u

next question is a 256 sd card big enough ?
format to Fat 32 correct is hbc region free ?

okay getting down to my main question

so how do you remove the hbc channel if say a wiikey update comes out to play nsmb or i just really want to ?

is hbc installed always even when i remove sd card or gecko whatever from link

or

is it always safe to update the wii to any new firmware with the hbc installed ?

what if i let the system update to (say 5.0 once it's available), will having the hbc channel brick my system ? seems like it did something in past reading others posts

what happens if my wii updates ? (ex. new games or would if a nintendo update will it brick system or will i need to check out info for every game backup) i wont make it update thou just wanna know

can anyone explain this guide better to me ? i have ntsc wii wiikey v1 4.1u - i have my own backup of nsmb that i personally made

i don't wanna brick my wii or have it ruined in the future

thanks for help its so hard figuring out info considering so may chips and softmod tools i dont want to mess with things like cios neogamma ect..

 

no i'll edit that post just saying i dont wanna mess with any of those forms of homebrew or softmodding

 

okay so if i follow the instructions on that link and put the files provided on my 256mb sd card i can play nsmb from my 1:1 backup once i open the hbc channel and install gecko and use that channel to play only that game ?

bootmii says
Warning!
This homebrew makes permanent changes to your Wii's flash memory (NAND) and should be used with caution.

all i wanna do is play nsmb on my wiikey v1
wish they would make an update they did for wiikey2

so this guide will install the hbc and gecko and work correct anyone verify ?

 

i have an original retail copy just looking forward to play a backup i made it myself with my lg & rawdump

thanks for your answers
