zsnes and 32 bit chroot issue

I set up a 32 bit chroot for zsnes, as per the directions given in the wiki. Standardly, everything works fine, and running

dchroot -d zsnes

loads it just fine.

I didn't want the chroot to have access to my home directory, though, so I commented out the lines in /etc/rc.d/arch32 that mount-binded /home to /opt/arch32/home. I copied my ~./zsnes folder to /opt/arch32/home/my-username/.zsnes, figuring that zsnes wouldn't be able to tell the difference between that and the default setup. However, without /home mounted, when I try to run zsnes, i get:

[greg@trollhammaren ~]$ zsnes

and then zsnes just exits. I get a lot of the same output when I run zsnes with /home mounted, but in that case it works. Anyone have any ideas what's going on, or how to fix it?

Show your edited script for mounting the other directories.

Re: zsnes and 32 bit chroot issue

Did you chown your home directory in the chroot?

I chowned the /opt/arch32/home/greg directory with the chroot-related directories unmounted, yes.
