flavors of bba and pso

[groovster]

i looked into as much info about the pso exploit as i could find...but i would like some verification from the pros

ok, i have a us version gamecube

1...will any old gc bba work w/ my console?

2...is there actually a us version of pso, or if i find an alternate version(jap,pal,euro), can i use the gamecube region free hack?

3...is it expected that there will soon be methods to make home-made backups of our precious games?
