Ok, the lockup with core=auto|dynamic was because there was stack access during port IO.

These are the file offsets (from the beginning) for the CGL functions used by 3DBINFO from VRITB170.CGL.

cglQueryScreen 0x10551
cglInitScreen correct offset at 0x10755
cglSelectRenderBuffer 0x12B39
cglClearScreen 0x127A5
cglSwapBuffer 0x12AB1
cglGetConfig 0x10E59
cglQueryFeature 0x15A19
cglClose 0x10E11

The rest will be decoded, rest assured.

(The previous version locked down the resource identifier to the expected value for 3DBVLB. This version will query it even if it's wrong.)

Run it with 1 as a parameter,
3dbvlb 1

Here it is.

Woohoo! That looks good. I'll add the results to dosbox in a bit.

and again (the VLB's IO port base appears to be 0x0204):

My logging text is wrong, but it's working correctly. The logical device is 0x00. The 0x76 is a register.

Here it is.

Thanks Gona!

Today's an ICR2 day, but here's one more for you Gona:

Thanks for all the testing BTW!

There is light at the end of the tunnel. Some games like Rebel Moon (1995) still don't detect the card, but Nascar Racing does. It fails to set the mode, instead of complaining about a missing 3D Blaster.

Here it is.
