128GB card must work but have you such data to fill it ?
@javelinface custom image is based on 0.5 with some things fixed/updated and new emulators & game
arch linux port take an other philosophy, pretty minimal with dedicated launcher based on file explorer and system packages based for future upgrades, but may require a bit of linux knowledge
for the twice you just need the os image and use dd or any program to flash it on the card
