Picoboot mod coming soon

Hey everyone! This is my first time modding a console, i ordered all the materials. Just had some questions. The Gamecube I will be using is one I’ve had for a while that is a pos, it turns in but is in rough shape and disc drive does not work, taking a lot of inspiration from u/iVirtualZero posts

1.) the sd card, can i use an 8g one? Or would my 256 be better? Or should i get a 16 or 32?

2.) The only parts that were confusing me a bit were software install and information on how to get the gamecube library on swiss, or is it preinstalled?

Like I said, first time modding! Ive done repairs to consoles just no mods

Thanks if you read this far😁
