McZonk has posted more info about theport of Quake 2 to the PSP, heres the news:
I think my Quake II PSP is the most configurable game on the psp now I added the options for select the analog nub behavior now.
Following options are availiable:
look: look up and down, turn left and right
move: walk forward and back, turn left and right
strafe: walk forward and back, move left and right
This should offer a good configuration to everyone. But there are a lot of actions in quake. So I added the headphone remote control too.
I worked on a basic layout for quake 2 togehter with Rikki Tikki Tavi. We did't agree in all points so it is good everyone can adjust controls himself. This is the basic layout for Quake II.
The blue options could be changed. The red options are hardcoded. You don't have to own a remote control but it is nice for extra actions.
