Oops! Accidentally deleted my last post.
This worked pretty well, but now I'm running out of space on the emulated machine. Is there a way to resize the CHD drive? I tried extracting the raw files, and creating a new CHD of 8gb size using the original files but IRIX still sees it as being 2gb total, which is way too small.

Is it possible in Irix to use multiple disks (multiple CHD's in MAME) to enlarge a single filesystem ? (like a 'Logical Volume Manager'). If so, you could theoretically create multiple CHD's, and then use these to increase the size of the required filesystems.
