PSP MAME4ALL v4.7r2 Hires is a port of MAME to the PSP.

Fixed from 4.7:

– 133 MHz in menu and while paused, for battery saving;
– VSync really works now;
– Corrected build configuration and Makefile, so sounds in various games are now back;
– Correct fixed, div2, sw scaled and sw stretched resolutions, with autocentering;

Thanks to for the news.
