Changing defaults (fast memory)

[supaman]

Even on PC it can make a huge difference in pretty much every game, its just that modern PCs are so powerful that fast men isn't needed, but it will help for weaker ones.

I am for this idea because there are a lot of people who just load games on the emulator and play them without looking at a the settings and if the speed isn't satisfactory to them, they complain so this will probably reduce that.
