optimize ram usage

[thedicemaster]

more ram usage doesn't automatically make it faster.
most likely ppsspp uses exactly as much as it needs.

you can see ram as space on your desk.
if it's too small you won't be able to work very well on it, but a 2x10m desk wouldn't make you work any faster than a 1x2m desk.

edit: i don't know what game you're using to test memory usage, but ppsspp's ram usage definately changes depending on how much the game needs.
i tried a few heavier games and their usage got up to 36MB, with the lightest i could find at 25.
a task killer's notification also isn't a reliable source of information(you shouldn't be using a task killer at all, the built in task management does all you'll really need)
the running apps/games list in android settings is more reliable.
