Hey guys,
I got my a620 and I LOVE IT!!
Anyways, I was playing around with it, and switching between Morphgear and PocketSNES BE, PocketNester, and some other programs. When I reopened Morphgear, the SNES Console was playing like it did on my 3955. I was thinking...NO!!!!!!!! Dun-Dun-Dun.
Anyways, I realized that I had been exiting the programs using the (X) in the top right corner. This, however does not stop running the program as it does in a desktop windows environment. I found that, first, I had to go to Settings-->System-->Memory-->Running Programs-->Stop (any programs that shouldn't be running), and then I had to properly exit the program by going to File-->Exit to keep them from continuing to run and using up memory.
I hope this hasn't been posted before, or I'd feel just dumb. Anyways, hopefully this will help someone!
