Is there anyone that can help? I'm having the same issue that is mentioned here: https://www.reddit.com/r/Roms/comments/1ahlpxe/help_with_the_adventures_of_panzer/. I'm trying to play it via Retro arch on steam deck. Thank you!

I read through the link you posted and this seems to have something to do with the mirroring setting. "
Somehow this rom got put with a wrong part of the header in the No-intro database specifically the "Mirroring" type needs to be changed to "Vertical".
To do this open the rom in FCEUX then go to "Debug > NES Header Editor..." then in the top left under "Version" change it to "iNES" then under the "PRG" section check the box for "Battery-backed NVRAM" and finally under "Mirroring" change it to "Vertical".
After that click "Save As" at the bottom and choose where to save the new fixed rom after you name the file what you want."
