Snes virtual console issue

Playing on the snes version (through the wii virtual console, titled FFII).

Outside Mt Ordeals I was grinding. At one point, when I was about to enter a battle, the screen went completely black and the game died and stopped working altogether. It wouldn't even let me reset or anything. So I switched it off at the wall, switched it back on again, and thankfully it was working again. Albeit I probably lost some unsaved data, but my save file from last time I saved was still intact.

Has anyone else had this issue with this version of the game??

I am now worrying that it will happen again, I sure hope not!

Just save often with the save states, in case it happens again.

Just wondering if it's happened to anyone else?

It probably has.

Just beat the game. Thankfully the issue didn't happen again. God knows what is was.
