GP2X Gp2xyaffs.img

[Orkie]

Has anybody managed to see what is actually inside the gp2xyaffs.img file which comes with firmware 2.0? If so, what is in there? I want to try and replace the root filesystem with my own files through the official upgrade system and I can't tell if this file plays a part in this or not. I've tried mounting it as loopback on the GP2X and on the PC (I build a module for my PC kernel) as well as emulating the mtdblock devices on my PC with block2mtd and mtdram, but I keep getting told that there is an invalid superblock, filesystem type or option when I try to mount it.

Alternatively, if anybody could give some instructions for making an image which is compatible with the official upgrade system, that would be nice

Thanks

It appears to be the root fs "/".

Any idea exactly what files? gp2xfs.tar.gz also seems to contain a lot, though I suspect that is installed outside of u-boot.
