Title: ADescent problem
Post by: lurkist on March 07, 2006, 08:18:11 PM

Found Descent in a charity shop today for 50p!
After figuring out that it is v1.0 I applied the Aminet patch and made it 1.5.  It now gets past the screenmode requesters and crashes with an ixemul.library window saying EMT trap.  Does anyone know why?  What versions of ixemul.library are people using?

Cheers

I've tried with v48 and v48.2, same problem.  Snoopdos says no problem at the point it fails, but earlier in the startup there was an ixnet fail.  Are they connected?

I have it working with 48.2. But I think it does work just with AHI 4.x, not newer, not older. And Warp3D PPC version doesn't work with the latest Warp, 68k does with bugs.

Same problem here, I can't get the Warp3D-version to work. I am using a BPPC/Mediator/Voodoo3 combo.
The ADescentPPC-version without Warp3D works without any problems though.

Make sure you have the correct ixemul.library for your processor. Does it have an FPU? IIRC, EMT traps have something to do with the FPU or something.

Also make sure that you're giving enough stack to adescent.

I would say the port is buggy because ixemul should not be used with system libraries ever.

With the version of ADescentWOSW3D, it's more likely a Warp3D problem, the version without W3D runs without a hitch.

Yes, it works with the earlier version of Warp3D, preceeding the Voodoo enhancements. I wrote to Hansjoerg years ago, but he hasn't had the time to fix ADescent Warp version.

Ah, that's sad. But anyway, thanks for letting me know. I wouldn't try anymore then...
