Mouse support?

[LunaMoo]

Mouse is supported from quite a while, but only for windows(it has to be enabled on the bottom of the controls config screen then mapped in control mapping screen), other operating systems will be supported when/if some dev that uses that operating system will implement it aka might not happen anytime soon since AFAIK nobody was working on mouse support for any other OS at least not openly.

Note that even on windows mouse works best when mapped to analog and even better if game is patched to use true analog input(most psp doesn't use analog and those which do often limit it to 8 direction and 2-3 sensitivity levels which sucks, but fits the hardware since analog thumbstick on psp also sucked and was nowhere close to real size gamepad or mouse accuracy).
When mapped to keys mouse will still input as analog and then translated to key affected by analog to key threshold which isn't configurable in the official version and as result it'll include slight delay.
