Model 2 video board going bad ?

Model 2 video card going bad?

I noticed that the roof at this stage of the Virtua Fighter 2 looks strange.

The textures in the middle of the roof look like they were messed up.

I looked for videos on YouTube of this game on a real machine and saw that the roof is rendered correctly and not like this.

Could anyone else who has this game send a photo of what the roof of this stage looks like?

It's a very small detail that I don't know how to complain to the person who did the repairs, it would be useful to have proof that it's not supposed to be like this.

I haven't seen anything bad like that on the other screens so far, I'm playing more to see if something strange like that appears on other objects.

Here's mine:

Have you tried running the memory check in the test menu?

Yes, it show all good

If I pay attention I see parts with messy textures but not as much as that roof.
Most of the game looks fine, only those who pay attention to detail see these defects.
Thinking a lot about whether it's worth sending it back for repair.

The texture roms are 24, 25, 26 and 27. You could try reseating them.

tryed an spare romboard , same game, nothing changed.

waiting for arrival of some more eproms , I will burn Sega Rally on my spare romboard and see how another game behaves.

this defect reminds me of tekken, weak in texture perspective correction.

Good point. Likely an issue on the video board then.

After a visual inspection of the board that came from the repair I found this, a short circuit, in the large IC near the edge, poor service, with a crappy 4x magnifying glass I found this short, how could someone who has an electronics laboratory not seen this and had the PCB there twice.

Did it fix it?

Did it fix it?

Yes

I was tired of arguing with the workshop, I did it myself, I would have to send it to them and I don't like this PCB walking around in the hands of the postal service
