Some times ago I also wanted to get any info about memory upgrade - for replicate purpose.
I sent message to Creative but unfortunately (and what could be expected) they won't help and redirected to forum.

Maybe someone tried reach somehow to old Creative employee?

Here you go. It seems like it read the primary adapter, though.

@gona
You didn't mention, and this is also interesting.
I am tried to run
Battle arena toshinden as 2nd works.
Rebel Moon as 2nd works.
Actua soccer as 2nd works.
Hi-octane as 2nd works. At the moment of exiting game it doesn't deactivate CGL api, last frame will be always shown.
Euro 96 does not activate CGL as 2nd uses soft render
Flight Unlimited as 2nd works.
Screamer rally as 2nd works.
Screamer 2 as 2nd works.

This makes me think that CGL tries to find PCI Id, vendor ID where it could be activated, not just bios.

The euro 96 I really doubt CGL is ever activated, coz shadows need to be solid.

Would be cool if in some reality CGL add on 3d card exist in form of powervr pcx, as PCI pass trough.

EDIT:
Please help on how to activate CGL on PCI for those games:
Euro 96
Whiplash
Fatal Racing
Battle Race
?

P.S. First VGA boot from verite 2200 agp
2nd is Creative 3D Blaster PCI

EDIT2:
activated EURO96 looks same way as actua soccer
activated battle race, well not just agp card needed its wrong, you actually need two pci cards, or maybe agp verite reports same vendor id and confuses battle race . i think its seek vendor id

still can't activate fatal racing.

EDIT3:
activated fatal racing/whiplash by deleting all the *.cgl files from fatdata folder and placing here only 170 beta 7 all cgl files.
and using only PCI as primary , black menus.

To be sure its CGL you could see checker board shadows stipple alpha much like matrox mystique do

Yes, I did not mention it because I have never tried it. 😁
I only tested the ones that do not work when the 3DB PCI is primary VGA card.
But it is a good idea, so I added it to the page as a note below the table.

I have idea but can t confirm, since I don't have creative 3d blaster vlb.
I think having two video cards in system makes ultimate CGL support.

The main trouble is to concatenate all video outputs)

And even more ultimate pc build could be done in theory to support as much as possible apis than vetz described a long ago)

EDIT:
You can play rebel Moon using CGL api on Matrox mystique for real.

I have got a CL-GD5462, a Creative one like this:
http://www.yjfy.com/images/oldhard/video/CT6320_2M.jpg
but CGL driver cannot accept the card, likely because it has not 00D2 but 00D0 device ID.

What if there is simply hex edit DevID from 00D0 to 00D2?

What type of cgl file is used by Star Fighter 3000?

What if GIGTE163.CGL will be used for PCI games to run on VLB? For Screamer 2/Rally .

i see there is no single game which supports FS ? (????I???.CGL FS Float Stack)

looking into Linked games deeply.

About Rebel Moon PCI version on PC with two cards Matrox Mystique (1st) and Cirrus Logics CLGD5464 (2nd) with L3DTB170.CGL , this not runs on CGL on matrox Mystique , reason this happens is game checks VenID and Dev ID , it founds those ids in systems and tries to activate CGL on Mystieqe , the QueryScreen fails and it uses SVGA mode with text corruptions and garbage pixels on bottom . So its just Software rendering which bugged, uncompleted .

while -VGA switch is okay.

I have bought a Diamond Fire GL 1000 card for reasonable price. I just finished with CGL testings. We have only the "Integer Register" type driver, so "Integer Stack" and "Float Register" applications cannot find appropriate driver. Diamond Fire GL 1000 also can not work as "2nd VGA" (add-on 3D accelerator mode), or this CGL driver not support this, so BattleRace; Fatal Racing/Whiplash are switches over to nothing and no signal. (3D Blaster PCI with CGL API can works as add-on 3D accelerator but with other APIs like Speedy3D API, works only as primary card).
Diamond Fire GL 1000 has a weak DOS VBE (2D) compatibility, there are 2D problems with Battle Arena Toshinden, Actua Soccer and Euro 96. With Battle Arena Toshinden it is temporary and easily playable, but with Actua Soccer and Euro 96 serious, it was a bit hard to me to get to 3D part.
Euro96_2D_on_Diamond_Fire_GL_1000.png
I think these problems caused by the BIOS of the Diamond Fire GL 1000 card, because with my Leadtek WinFast 3D L2200 (also a Permedia NT card) there is no problem with 2D parts of these games.

Nice work! I was looking at this stuff a bit today and figured I'd pull up the thread to see if there were updates. Looks like. 😀

A couple things:
- I think these "second 2d card requred" games are fixable so that they don't require 2 cards in the system. When I looked at Battle Arena, they do this weird thing before they even initialize CGL, they put the VGA into text mode. I think it might be possible that this stops the CGL library from working on some cards when it is the only device in the system, so nopping this code out might fix it.
- Do you have BIOS dumps for the FireGL 1000 and the Leadtek? I think it would be interesting to take a look. 😀
- Today I am working on patching the "21st century digital boy" demo so it works for all CGL boards. When those guys sent me their CGL headers and lib they also sent me the source file for just how they interacted with CGL (not the drawing, just the routines). They have a special check for the Verite like so:

Copy code to clipboard

1//
2//  Rutinas con el interface PCI de Yann, porque si no, las CGL no
3//  detectan la presencia de una 3D Blaster :-?
4int Detect3DBlaster() //verite
5{
6   PCI_Init();
7   if (!IsPCI) return(0);
8   Device3DB=PCI_FindDevice(0x1163, 1, 0);
9   if (Device3DB==0xFFFF) return (0);
10   Is3DB=1;
11   return 1;
12}

and then when they initialize, they specify they only support the Verite card:

Copy code to clipboard

1#ifdef HOTCGL
2#ifdef CGLFLOAT
3  ErrorCode=cglLoad("", CGL_BOARD_VERITE_REV01, CGL_CDL_FLOAT);
4  if (ErrorCode != CGL_SUCCESS) return(fnBad);
5#else
6  ErrorCode=cglLoad("", CGL_BOARD_VERITE_REV01, CGL_CDL_FIXED);
7  if (ErrorCode != CGL_SUCCESS) return(fnBad);
8#endif
9#endif

Where the board IDs are:

Copy code to clipboard

1//-- Board IDs for HotCGL
2#define CGL_BOARD_AUTO                     0x0000
3#define CGL_BOARD_GIGI_REV01               0x0001 <- GiGi
4#define CGL_BOARD_PERMEDIA_REV01           0x0002
5#define CGL_BOARD_GLINTTX_REV01            0x0003
6#define CGL_BOARD_PERDELTA_REV01           0x0004
7#define CGL_BOARD_VERITE_REV01             0x0010
8#define CGL_BOARD_CIRRUS_REV01             0x0101
9#define CGL_BOARD_LAGUNA5464_REV01         0x0102
10#define CGL_BOARD_MULTI_AUTO               0xFFFF

Something interesting here is it looks like there were 7 chips supported in total for this version of the SDK, and it looks like we are missing CGL drivers for:
CGL_BOARD_PERMEDIA_REV01: Permedia (no Delta)
CGL_BOARD_GLINTTX_REV01: GLINT TX (maybe the early PCI prototype board for 3DB VLB game developers)
CGL_BOARD_CIRRUS_REV01: a mystery Cirrus Logic that isn't the 5464

So I think I can patch the demo to ignore the PCI VID/DID check and support any CGL driver (with varying results, of course). Right now my problem is since I don't have full source, I need to patch the binary, and it is packed with PMWLITE - I'm not sure how to unpack it.

Decompression tool found http://justsolve.archiveteam.org/wiki/PMWLITE

also please explain on how you dissassemble *.CGL files, what is need to be used?

Actua Soccer have 1.2 some CGL source code H and LIB files
Urban Assault have 1.2 some CGL source code and they different to Actua Soccer H files
21st demo have 1.60a some CGL source code H and LIB files

Does anyone know if there is a Bios dump for the VLB card anywhere? I have searched high and low but cannot seem to find one.

In theory yes, but 3D Blaster PCI not really likes non PnP boards, and 3D Blaster VLB not likes PnP boards, at least in my only PnP board with VLB: SOYO 4SAW2 (a Socket 3 - SiS 496/497 board) 3D Blaster VLB got strange resources. Rebel Moon can't start with it. With my default 3D Blaster VLB board the 3DB PCI not found as 3D Blaster hardware (even if 3D Blaster VLB is not present). Much better to build a separate system to them.

3D Blaster VLB is an add-on card (like Voodoo 1-2). Although have limited 2D, eg. Win 3.1 driver exist (this not too impressive, the average performance in 256 colors, only 60,7% of the top Win 3.1 VLB performer), but the card have no Bios.

There's a slight byte offset error with one of the decoded streams (cglSelectRenderBuffer or cglClearScreen).

This would suggest cglSendStream should start of 0xEEDD+0x2434 and sure enough at file offset 0x11311 there're opcodes 52 , 51, 56. These are push instructions, which is normal for register based parameter passing.

Similarly cglGetPixel appears to start at 0x12321. Well something does.

good news, congratulations!
well i reading cgl files by hex-editor, by eyes and source's available to me , struggling, can't say something new for now, you look much further, and already know everything even more than me)

Hey RaVeN-05!

I think the float version of the library can be made by changing the first function name (string ends with ir, Integer register). Stack should be is and fs. It would be great actually get this working. Exciting times ahead.

21cdb and toshinden don't appear to use ir. I'll do some tests soon and hopefully this can be up and running soon. Vlb games will probably have to be patched. G*. Cgl driver should probably help.

Raven-05,

Ignore this. It fails at cglQueryScreen. The mode number probably doesn't match.

if you still have access to your hardware, you could try patching:
cglBoardPresent_: pointer 22A4, file offset 0x11181

file offset 0x11181 with:
Replaces the bytes here:

10:  31 c0                   xor    eax,eax
22:  c3                      ret

to see if it runs the CGL apps run on a V2000. I could put in the legwork, but I'm a bit swamped. Forcibly disassembling it with Ghidra does show a series of protected mode calls to INT 1A function 0xb101 (PCI device query).

I don't know whether eax should be set to 0 or 1. I don't have the prototype for this function in the CGL headers that I've got.

Update: I think it should return 0 on success. One of the branches returns 0, the other a something else. DeepSeek seems to think it's a memory allocation when some of the parameters for the int 0x31 call contain 0x1A (real mode interrupt for PCI device query) and 0xb101 (a specific type of subquery, the same one vQuake uses to detect Rendition cards. I'll test this now, instead of wrapping.

If that doesn't work maybe:

10:  b8 01 00 00 00          mov    eax,0x1
25:  c3                      ret

There maybe other reasons this won't work.
