I can run late 80s or early 90s game 100% with MAME .89 (maybe .104) + hwstretch on a 750mhz XP SP3 machine.
However, I have the inclination that Android handles resources differently. Regardless, you can't do a thing with an app that isn't wrapped in Android widget format. Android phones are not PCs.
Consider it high comedy....sincere tragedy....whatever...don't take it personally.
