Smashstack and SD cards

[PAINT]

Hi I'm really new to hacking and mods, and as I was reading up on smash stack and the n00b guide, and something confused me. With smashstack I get that its meant to be and SD card only, but does it HAVE to be 2 gig or less? Furthermore, does the unofficial PAL version work just as good as the official US version? Also with smashstack in comparison to the n00b guide, it states that after running it you delete the SS, but the thing is you have to go through the process each time you want to play with HBC, so would I have to keep it?

I'm sorry it's just confusing me heavily and I just want to use some of the awesome stuff put on here! >w<

Thanks for taking the time to read and help!

The sd card has to be 2 gig as for the pal version I'm not sure if it would work or not
