Just thought I'd mention that I wrote a ProDOS program selector years
ago that I called Selector v1.0.  I used it on a 3.5" disk that I had
transferred some DOS 3.3 games onto.  I added an option to "zap" the
text screen memory protection before running a program to avoid the
"NO BUFFERS AVAILABLE" error message when the programs tried to load
themselves over the text screen.

I only used this program on a 3.5" bootable disk as I didn't want
anything to go wrong on my hard drive.  This also only works with DOS
3.3 programs that are contained completely in one file and do no disk
access because the DOS 3.3 disk routines are not in memory when ProDOS
is running.

I even wrote an article for "II Alive" magazine about the POKE to
disable ProDOS' text screen memory protection.

If memory serves me correctly, I had a version of Moon Patrol on that
disk that ran fine on my IIgs and I believe that is one of the titles
that the original poster had problems with.
