I open the file up and try to play it, but the "Link" sprite only moves one space and then the quest appears to freeze except for the monsters/background effects...
I am using Zelda Classic version 2.10 to try to play this quest if that is relevant to the problem, however, I would hope to not have to install a lower ZC version in another folder just to get one quest to work...
This happens to me if I don't move Mario at the start, this fixes if I keep pressed the up arrow while the game's loading.
I even tried that and I still get the same problem...
I get that problem all the time. Just press esc, go to Quit, then select Continue on the next screen. That fixes it. Note that you have to do this everytime you start the quest from that file select screen...
