Hi there,
I would like to announce to the Allegro team and users another PSP Allegro 4.2.2 (last stable version) port.
I've posted about it in psp.scenebeta.com and pspdev.org forums.
Not yet in the MAIN place ... shame on me

The graphics driver is working with a RAM-RAM and a RAM-VRAM hardware blits although it needs some optimizations for 640x480 and bigger resolutions and support for virtual screens.
A mini keyboard driver is implemented too and the "magic" main code so the Allegro apps are fully portable.
For the sound driver I'll use the Allegro mixer.
The timer and joystick drivers are not implemented yet.

For the main testing (apart of the Allegro examples) I use the great Humphrey Remake by Ignacio Pérez Gil.

I expect a fully version ready to deliver as soon as possible.
