8gb sd cards work fine on HBC. I've tested 4 different brands (Kingston, Transcend, Sandisk, and one offbrand one).
But there is a trick to it. Most of them will not detect initially.
You have to hit the "Home" key and choose "Reload", then upon reload the card will detect.
Its something I stumbled onto by accident when I thought my first one didn't work.
I'm curious about Cygoku's problem, though...
I tried all the cios60 installers and could never get one to download and install, so I ended out seeking out the patched wad and installing it through this same Wad Manager just like he did, but it works fine for me.
I also gave that wad to another person on this board and they had no problem installing it through this Wad Manager.
I wonder if there is some hang up when trying to install it twice?
I'm considering downgrading to 3.2, installing preloader or starfall, and then trying installing the wad twice to see if it bricks me (since it would then be recoverable).
