Software News   Software News : Version 1.1 of Allegro released (and some games)
   posted by Hitman on 13-Jun-2009 21:48:22 (3172 reads)
After months of promises to Spot that I would release an updated version of Allegro, I finally got around to it. It's much more advanced and stable now, which is something that users will notice because it allows Spot to start releasing lots more games. The release games were just a "taster" to go along with the early version 1.0 of Allegro.

And speaking of games, I've recompiled Ghouls 'n' Ghosts Remix to the latest version, so now it has an extra level and nicer particle effects when you kill monsters.

So go grab the Allegro shared object from OS4 Depot, 'cause Spots already started releasing games!

i know something is being done about open sonic, but not by me. :)
i uploaded a bunch of stuff to os4depot today. nothing to be overly excited about, but the allegro font editor is nice for example.
more to follow, be so sure!

hitman, this update is miles better than the old version, thanks for the update, finally. :)
i have found some issues today though, ofcourse ;) i will mail you about those soon.

the slow times on os4depot are over! weee...

and, IamSONIC, congrats on your first port!

Yes it's maturing now - all that hard work is beginning to pay off! I don't know if I'd have started this project if I knew just how much work it would be!!!

BTW, when you upload can you mark the uploads as Allegro in their description so that it's obvious. Then I can download them all to check for compatibility with future versions of the library.

Hi.

Allegro now only works with OS 4.1, not with OS 4.0. So if you try to run an Allegro game on a 4.0 system then this is what will happen. Mind you, you should only get the "nice" error that Allegro prints, not the crash. Unfortunately most Allegro games are pretty badly written so if Allegro fails to initialise then they crash as they don't do any error checking.

What OS version do you have? I really didn't want to make Allegro OS 4.1 only but unfortunately there are some pretty nasty bugs in the old OS 4.0 version of elf.library that prevent shared objects from working with the latest SDK.

Ah well looks this looks like another good reason to upgrade from OS4 Final as i was
also wondering why it was non-functional for me also.

Is there anyway you can reduce the memory requirements ? I had about 85MB free after booting and I tried the Ghosts 'n' Goblins remix and it started loading the graphics for the game and ate up all my RAM and crashed... :(

Maybe load/unload graphics/objects as needed?

@HammerD

Unfortunately there is not much I can do. GGR does take a lot of memory and I find myself that on my 256 MB system I often need to run it from a clean boot.

The problem is not with Allegro but with the games themselves. Most of the games, even if they are fun to play, are not very well written, because they are not written by professionals but by "bedroom coders." So as such they don't have much in the way of error checking and the code is often very poorly done. So they work, but as soon as something goes wrong - BOOM! And because they come from the PC world they are very memory hungry, as you have seen.

The only way that I could do anything about that is to start actually editing the source code for the individual games, which I don't have time to do. I could make GGR very lean on memory but it would take weeks! I'll only do that if the game is particularly good and really won't run well or at all on the Amiga without some work. Otherwise I would spend my entire time just editing games and never getting to add new features to Allegro or to work on my other projects (which I really must get around to releasing one day)!

Sorry I can't give you a more pleasant answer!

Hi Cap.

Did it crash in the same way, with the error followed by the crash? I might make the allegro_init() function exit by default to avoid this kind of thing in the next version. As I said to someone else in this thread, most of the games do very bad error checking.

Hi Hitman, would you ever consider a port of Allegro to AROS too? It would be really helpful...

@paolone

Sure, an AROS port would be great! But I don't have a PC. The sources will soon be in the official Allegro SVN server so after that anyone can get them and compile for AROS, Morph OS or OS3.

I should really have put them in the SVN server already but have been lazy.

@Tuxedo

I'd like to get to the bottom of this.

Can you do me a favour and type:

version elf.library full

And let me know what it says? Thanks.

I got:

elf.library 52.4 (24-Mag-2007)


Maybe a "bit" old right?

Where to get a newer version?

So after a few days when the new allegro lib is out ...

when people running allegro stuff and it crashes, either they have:

- Not installed the elf library update from Hyperion website
- Not installed newest allegro library
- no AmigaOS 4.1


@samo79
Open Sonic iss already ported and will be released when the last fine tuning has been done

@spotUp
thx 4 compliment

@hitman
thx 4 your great work on allegro
