Visual effects missing (Space Station Silicon Valley)

A number of visual effects are missing from Space Station Silicon Valley. Some could be issues with the z-buffer, others look related to shaders.

The 2D logo and 3D spaceship are missing from the title screen!

Transition effects between shots are also missing: Several screens split into a grid. ParaLLEl just cuts to black.

Sprites appear in front of everything else, regardless of where they should be in depth..
Collectibles and flowers appear in front of trees and land that should obscure them.

This purple pickup is in front of the dog's head instead of behind it.

The pause menu is supposed to have stars moving to the left, leaving trails. The stars do not render at all.
The stars on the pause screen are supposed to be occasionally interrupted by a tv static effect. This instead flashes plain gray.
Also, the small screenshot top-right is missing.

Tested with:

• Devices:
  ** Windows 11 x64, nVidia GTX 1650 Ti, Vulkan
  ** Samsung A52s 5G, Android 14/OneUI 6.1
• Apps (fresh install):
  ** 2025-08-24-RetroArch_x86_64
  ** 2025-08-24-RetroArch_aarch64
  ** 2025-08-24-RetroArch_ra32
• Cores:
  ** ParaLLEl N64
• Games:
  ** Space Station Silicon Valley (Europe) (En,Fr,De,Es,It,Nl,Pt)
  ** Space Station Silicon Valley (USA)

Start by reproducing the reported effects in ParaLLEl N64 using the listed Windows/Vulkan and Android configurations, then compare the intended and actual screenshots for the title screen, transitions, depth ordering, pause menu, and TV displays. Done means the missing effects render correctly, sprites respect depth, and the reported screens match the intended behavior.
