Re: psx4droid problems :-(
(tl;dnr= set screen refresh rate to 30.)
Take back everything I said about lag because I had no clue what I was doing then, and was using default settings. Silly me.
Menu < Settings < Screen Refresh rate
Default = BAD (According to me and my priorities XD)
I set mine to 30, which seems to make everythign run the fastest. And this will be noticable immediatly. I was playing CTR (a racing game) and as soon as I resumed the match, everything went so much more like the origional. Crash 2 and Spyro 2 actually made me feel like the levels were totally playable. To be blatently honest, I don't know what this setting fully does or what gets taken away from us in turn for better speed, but I don't care. With the lag it origionally had, anything was worth an improvement, especially of this magnitude.
EDIT: Also gives dramatic sound improvement. Still not perfect, but bareable now depending on the game.
