I tested all my games out with a Disk ][ card and still had issues.  It
does fix some problems, but not all.  In the end I decided that for the
handful of IIgs games that I'd want to play (I also have an Atari ST,
so I can play 90% of the games anyway), it's not worth bothering with.
I'm keeping my IIe out and put my IIgs in mothballs.
