Software News   Software News : Allegro for OS4 update
   posted by Hitman on 10-Jun-2007 23:12:10 (5906 reads)
Hello everyone.

Well after much hard work I am happy to say that Allegro is now running on OS4. It still needs some work in the optimization department, and to increase the number of games that can be ported it will need some extra libraries to be ported as well. But these can come later in stage 2.

read more


You may be interested in looking at some screenshots!

Here is a remake of one of my old favorites from the c64, Sword of Fargoal:

Sword of Fargoal

And for those Ghosts & Goblins/Ghouls & Ghosts fans:

Ghouls 'n' Ghosts 1
Ghouls 'n' Ghosts 2

And yes, it's just as damn hard as the originals!!!

Plus of course the obligatory Tetris clone:

Vertris

I am going to spend this week cleaning up the currently written code and hopefully by next weekend I'll release the above games (and some others) for people to play and to report any problems they find.

Like the SDL port, now that the main work is done, Allegro will continue to be slowly improved over the coming months to make it more robust and usable. The people on the official Allegro mailing list are very helpful and friendly, so I'll get the code into their Subversion repository soon.

Now I have one favor to ask! Good Allegro games are a bit difficult to find! Most of the really good ones don't come with source and many others are either rubbish or are difficult to port. So if you find any really good games that come *with* source, post a URI to this thread, and either I or spotUp or ToAks will take a look at them!

Nicely done! Is it a "native" port sitting on top of graphics.library and/or picasso96, or does it rely on SDL?

@CodeSmith

Yes it is native.. its all PPC code and running via native OS4 API. and no there is no SDL connection.. if you want to you can throu SDL out if you want to.

And the news is out! :D
I've spent a couple of hours looking around for some stuff for the compiler to crunch. I found some really good looking stuff, but that was closed source. I've written the authots, who also are swedes.. and swedes likes amigas. one can hope! :)

Excellent news indeed!

On a side note where can I get that groovy looking War of the worlds wallpaper in the screenshots?

Great work ! Hope we'll find some more games on OS4 with this library.

PS: How can you have a 4C temp on your CPU : are you living in a fridge ?

Legendary Legions - All units have been taken from Celtic Legends (an old Amiga game), the concept is a hybrid of Celtic Legends (its not clone), Heroes of Might & Magic and Civilization.

Is the port done like a OS4 .library or is it only a link lib ?
(Hoping for the first). So that if new versions of Alegro comes out we dont have to recompile all things already ported. Like with the current SDL ports.

Alex The Allegator 4 (from Free Lunch Design) is a fun game with source available. I just started looking at it this weekend for a GP2X port. It needs DUMB (a mod player library) although it looks easy to remove that requirement initially simply by removing music support.

Allegro is a good opportunity for some new ports, but it's also a really good opportunity for any wannabe games makers/programmers out there. It has a really easy to use API (I think easier than SDL) and is a great opportunity for anyone who'd like to learn C and make some simple games. It's kinda the AMOS of C programming.

Does this port rely on any OS4 specific API's? I'd like to have a look at what's involved in porting to OS 3.x and AROS (I don't have an OS4 capable system although I remain hopeful that it will happen sooner or later).

EDIT: have a look at F I E N D too, requires Allegro and FMOD.

Excellent!

But good games are hard to find ? I thought this was the whole point of the port? That it would open the doors for good games to be easily ported.

Anyway, I'd love to see Mythic Blades. It's commercial though.

Perhaps a port of UFO 2000 might be possible as the sources are available.

I want an OS3.x port also And i hope so

Anyway, good work, this library will bring a lot of more software for Amiga

It's because it is not setup properly. Apparently you need some hardware in order to check its temperature and then calibrate it with the docky. So I only use it to show me how much CPU time is in use.

And as you can see from the screenshots, the CPU usage is often 100%! This is because I have not yet finished the timing/sleep routines.

MEKA is a very good Sega Master System/Game Gear/ColecoVision emulator which uses Allegro library. It's a good opportunity for AmigaOS 4, because currently the SMS emulator for AmigaOS 4 is buggy and crashy.

Currently it is just a link library as it depends heavily on the C runtime library and as far as I know you are not supposed to use that in Amiga .library files (although simple functions like strcmp() are ok).

There are plans for a shared library version in the future, although I can't go into details at the moment. But it shouldn't be as much of a problem as it was with SDL as there are far fewer games for Allegro than for SDL.
