Supermodel Forum

So I have this up and running on my Intel NUC 8i7BEH on Ubuntu 18.04.4

To get the new3d engine working I have to set a GL Version override 3.3+
for example:

Code: Select all

#!/bin/bash

cd /opt/retropie/emulators/supermodel/
MESA_GL_VERSION_OVERRIDE=4.6 ./supermodel
/opt/retropie/emulators/supermodel/von254g.zip

Now most games run fine with this override except Virtua On, which just black screens at boot.
Problem is that I don't receive an error. So I'm stuck using the legacy engine. Here is the log:

Code: Select all

This is what I get when I dont use GL Version override:

    Developer:      Sega
    Year:           1998
    Stepping:       2.0

error: vertex shader lacks `main'


Also, Star Wars has two problems.
One I found a fix for concerning the Death Star II unshaded interior, although its kind of glitchy..

Code: Select all

if (!m_shadeIsSigned) {

Change to

if (true) {


The other is rainbow speckles on the Death Star planet in the Yavin stage.

Any ideas on whats going on or edits I can make before compiling?

Thanks for the emu and any info I may use.

Can you share photos of the problems? Commenting out the signed shading code isn't really a fix -- that code is there for a reason. The question is whether the Death Star is actually being rendered incorrectly or whether this an issue with your particular graphics chipset and drivers.

Well the Virtua On problem is a black screen at boot, not much to show.
I'm just stuck using -legacy3d for that one.

Here goes the Deathstar II without the fix:

Here goes the Deathstar on Yavin:

I have reverted to ubuntu's default graphics, padokas stable and padokas bleeding edge (which Im back on)
It doesn't seem to make a difference.

I also tried changing texture2DLoad to textureLod before building too.

I see and can confirm this bug is indeed happening. Unfortunately, we don't know how to fix it or what causes it. Coincidentally, I have a save state just prior to this tunnel sequence. The pipes look correct during the cinematic transition sequence but as soon as the game switches to the first person perspective, it is broken. Our hypothesis has been that some special Real3D registers are written to enable signed shading mode. But none of these are accessed by Star Wars Trilogy. So we aren't sure what's going on.

What about the rainbow speckles on the Deathstar in Yavin on the second image above?
At first I thought they were lights but I watched videos of the game and saw that, their not there.

Do you know which commit this shader problem happened around? I can always use an earlier build just for Star Wars Trilogy.

The rainbow speckles might appear on the original hw but are so low res we don't see them?
You are rendering at HD resolutions.

I'll checkout the lighting issue when I had some time

Just had a few minutes .. had a look at this star wars thing. The gfx engine is working as expected, but the jtag values are never updated. Not sure why. Only thing I can think of is those patches that were applied

<!-- Additional patches from MAME for test menu -->
<patch region="crom" bits="32" offset="0xf776c" value="0x60000000" /> <!-- unemulated JTAG stuff -->
<patch region="crom" bits="32" offset="0xf7770" value="0x60000000" /> <!-- "" -->
<patch region="crom" bits="32" offset="0xf7774" value="0x60000000" /> <!-- "" -->
</patches>

If you tested with a save game before. You have to start the game from a fresh boot and play all the way through to that point. Simply unpatching it and loading the save state doesn't work I don't think.

If you could test this and get back to me it would be helpful.

It didn't change anything. I did a full run, no save states with a fresh nvram too.

Did you try removing the patches?
they are in the games.xml file

Yes, I deleted those patches from out of the games.xml Then I did a full run with no save states and the tunnel is still dark..

Now when I apply the code from my first post above, the tunnel is fine. Strange..

I'll just keep two versions of supermodel executables with one named supermodel_swt just for star wars for now.
