Hi all,
I would like to share my Allegro PSP WIP :)
A simple graphic driver and the a mini keyboard driver using the PSP controller are implemented by now. It compiles and links with success some Allegro examples and the excellent Humphrey remake (the main reason for converting the library :P )

Two Allegro examples:
http://album.miarroba.com/diedel/0/6/
http://album.miarroba.com/diedel/0/7/


The Humphrey remake:

In PSP:

http://album.miarroba.com/diedel/0/9/

Greetings!

Hi,
a beta version of the library is ready to use. It is possible to add it to the ps2dev svn?

Thanks.

Great job, I know how much work it is. (Well, I had no prior PSP programming experience)
You don't seem to have an IR keyboard driver, you can use mine if you want ( Shouldn't be too hard to fix up. Requires kernel mode :( ) - http://tehsausage.com/allegro-psp/download

I think I've pretty much given up on mine now, too lazy to implement scaling etc.

Edit: You could use the timer (and possibly analog mouse) driver from there too, they're not perfect (thread synchronization mainly) but better than nothing.

This is my first PSP programming experience too.
As you say it gets much time but actually I have enough of it to spend :) I like this project.

You know the projects are never finished :) so you can continue anytime.

Thanks man, I appreciate your friendly help. Technically, joining our codes the port is near complete :)

Great!!!


Now, I need to ask you a question... Can you work a porting of your library for Nanodesktop? I hope that you accept... You can contact me at cameracafffe@live.it for further informations...

you can see from http://visilab.unime.it/~filippo/Nanodesktop/PSP_PSPE/Screenshots/ndPSP_Screenshoots.htm some screenshots of some nd features: as you can see, nanodesktop is a very very good SDK, and his developer (Filippo Battaglia aka "pegasus2000") wants to port Allegro library on his library: can you help him?

Exact! Nanodesktop is the most important PSPSDK... your Allegro Library is very very important... if you accept, we can create all what we want... scientific application, games, emulators :)

Thanks sauron_le_noir.

I'll add it to the last version of the library.

I wrote you a PM.

Cya.

Sorry if this is off topic, but i'm just curious...

Is this in anyway related to the legendary Allegro graphics/gaming library from back in the MS-DOS days (which is still maintained today)? Or is the same name purely coincedental..?

EDIT: Sorry, you failed to mention that this is a port of THE Allegro library. WOW. Well done! Very awesome!

@diedel:

In any case, I'm writing a new version of Nanodesktop that shall
support sprites. I thought that this can be useful in an Allegro
porting. I've open a thread in this forum for the proof of concept.

Here a screenshot:

http://img82.imageshack.us/img82/6527/screenshotftk.png

I hope that you can create a version of ndAllegro in the future...
:)

thanks for porting allegro:) btw are you working on making the addons(allegroGL, jpgalleg, loadpng, logg) usable with the psp. From what i can see all the dependencies like libpng, jpeg, zlib, ogg and pspgl(which is basically a subset of opengl) are already in the svn repo
