Ok, well the NAND I've be working with is too big to fit on any SD cards I have, so I made a copy of it and cut away a bunch of stuff to bring it down in size. Anyways I was thinking that because the NAND was optimized for uneek it wouldn't work on an SD card (how little I know). Well, surprise, surprise, the NAND works fine when run off an SD card.
However, it could read the NAND fine, but when I tried to boot a VC n64 title I received the following error:
ES_Identify...ERR: (identify) ES_Identify (ret= -4)
ERR: (bootTitle) Identify failed
