OK, I decided to try PearPC again. Unfortunately, I could not get it to
boot, on either the MacOS X 10.2 installation DVD or the Yellow Dog Linux
CDs. With MacOSX, when I have prom_env_machargs = "-v", it
complains about /dev/rdisk1s1s2 having overlapping extent allocation (What
device is that anyhow?), does
something akin to an fsck, fails and exits (the HD is still untouched). From
http://wiki.pearpc.net/index.php/Files:BasicConfigurationFile:
## machargs: set to "-v" to get a verbose startup. this will
## often fail in Mac OS X 10.2, 10.3 and 10.4.
So I disabled it, just for kicks. Still fails, in about the same time, only
now I can't see what it's doing. In either case, the executable prints out
(after the GPL thing)

I've done this before, so it should work, but it doesn't. Any ideas why
not?
Wy config file (minus the comments) is:

Yes, the dir stays mounted, as it's my cwd.

That video.x needn't be executable (I think), but that's the way it came out
of the compiler.
