Good review. Have you tested out Drastic as opposed to the Desmume port (included in RetroArch)? In my experience, it runs most things I've thrown at it fullspeed on my Galaxy S2 sgh-989 (a good bit less powerful than the g5a). It should be noted that Drastic does cost money, but it is indeed highly functional. I'm wondering if the screen is accurate enough to allow for solid performance in games that use the touch screen (assuming a stylus is used).
