Trident BIOS files broken

[marcin-chwedczuk]

Looks like the Trident VBIOS files that you are using are broken e.g. missing 55 AA signature.

You may try to use BIOS from this site:
https://www.vgamuseum.info/index.php/component/k2/item/443-trident-tvga9000i-1
https://www.vgamuseum.info/index.php/component/k2/item/download/715_ed43663a5d246ed4a656a2ea1fae5212

Looks like some dumps from the physical cards are broken. I am still investigating this. But BIOS files from vgamuseum mostly works and I can decompile them in Ghidra.

I hope that helps. Thanks for your work!
