I guess more generally I am stuck on a single point:
I want to reinstall Irix 6.5 so I can get a larger disk image, but I absolutely cannot figure out how to switch CDs within MAME while the machine is running. There's no MAME menu to open, no MAME hotkeys work (as previously mentioned in the thread) and despite a few hours of Googling I haven't found any references to how this is done. Clearly someone's gotten it working because the 65.chd exists, but how did you guys do it? I've read the entire thread (and subforum) like three times but I haven't seen any explicit reference to this part of the process. I just want to switch CDs in the middle of emulation so that I can install IRIX 6.5 with a larger disk image available.

Thanks for the help and sorry for all the posts about this.
