OK folks.  I've searched for this answer..  and nothing has come up.
I'm using a good set of 2600 roms.  So, I know it's something that I've done wrong.. but, dang if I can figure it out.
Any file name that has a 
-  in it.. won't play (which is most of them, when you're talking the good2600 set.  If the file is walker.bin, then it plays fine.  If it's walker [!] [pal].bin .. then forget it.  It says it can't find the file.
I'm assuming that the []'s are screwing up the command line.
Anyone have a solution for me?  thanks guys!
