I think what he's asking is if there are some Arexx bindings that support SDL.  There are for other languages.  SDL is just an API, Arexx a scripting language.

There are perl bindings for it, so why not?  

What I'd like to see is Mesa ported to AGA... :D  of course that would probably perform horribly, but could allow for some other stuff to work.

IIRC Brian Paul wrote the first version of MESA on his Amiga.

I should have elaborated more :)

I wasn't asking about Arexx the language.  I accept input from Arexx but I don't give that language any special treatment.

When I said "arexx" I meant the Interprocess Communication API part of arexx.

Games and apps need to be able to accept commands from other tasks running on the same computer.  SDL supposedly allows programs to run and perform the same functions on multiple platforms.  Interprocess Communication (like with arexx) is a function my game needs for scripting language support.

Interesting.  I did a search and it looks like you could be right (I didn't find the actual article that says it's where it started).  I found quite a few useful things about Mesa, the Amiga and 3D rendering engines.  Specifically that at one point Crystal Space ran on an Amiga.

I would love to see OpenGL running on my Radeon.

The SDL strikes again :)


It's very early days (only a few hours work), not sure how it will run real hardware yet.

Thanks, yes I will at some point :)

This is only after a day's effort so lots of work to do before I can release something worth beta testing.

Hey nova
Congrats. Looks like the speed is decent. After some optimization it should be totally playable right?

To all the 030 whiners GET AN 060 :)

So what is the story with SDL and RTG?

Many many years ago I was going to port all my games over to SDL/RTG.

But SDL was megatremendously sloooooooooooow.  It had been out for a few years yet nobody had ever optimized the algorithms at all so it was totally completely worthless. :(

Now that a gazillion years have passed, is SDL a good option for RTG gamecoding now?

In a few months from now I am going to be in need of a properly working SDL that performs reasonably well on RTG cards with 128MB VRAM.  Does such a SDL currently exist?

Will SDL RTG for example on one of those Radeon 256MB gfx cards everybody buys these days: will SDL use the Radeon SUPERDUPER BLITTER from hell to do high speed blitting?  Or does it still use the CPU to move each pixel one at a time like it used to do?

Hiya,

If I ever get the time I'd like to add RTG support to my AGA SDL and use it to do a new port of ScummVM for RTG Amiga's.

From what I've read, Amiga RTG pixel formats are a mess (non-standardized), that is why blitting can be very slow, esp when you mix color formats.

I can test that too!  :D

Is there any of the old SDL/RTG software out there?  I know there is an old version of Exult, but I'm not sure if the Amiga port used SDL or not.  Maybe I'll give it a shot and find out, then report.
