There is no ISO filesystem on SGI CDs, they're all efs. They should still work just fine with MAME though, since MAME doesn't really care about the filesystem on the CD

When we say iso, we actually mean pure 2048-bytes sector dump. The filesystem encoding is not looked at.

The install cd we tend to use is 812-0336-001. https://archive.org/details/sgi_IRIX_5.3_for_Indy_R4400_175MHz

The SGI CDs with a .img extension segfault for me as well but renaming the *.img files to *.iso fixes that and allows me to use the images without any other issues.

Indeed, renaming the file to .iso works. That seems like a bug. It still thinks it's a cdrom, but dies with a null pointer in read_partial_sector().

ISO files have no magic numbers or other identifiable characteristics, so we have to rely on the user telling us what the file is.

I've hooked up the controller ports to the Coleco Game Adaptor for the Spectravideo SVI-328 computer, so the games are now playable:

Command line used for this was:

Code
mame64 svi328 -exp sv603 -cart2 dkong


There is an MSX Game Adaptor too, but we don't have a ROM dump for it.
