I'm trying to run green stars on pj64 1.6 but I get the error "Executing from non-mapped space." I try to change the memory size to 8 mb but when I change it and press ok, it doesn't save my change. Any idea on how to fix this?

NEVERMIND. I fixed it :D. All I did was go to the "advanced" tab in settings and set default memory size to 8 mb.
