Consider a modern engine with shaders that enforce those arbitrary limits.

Unity shader asset: https://assetstore.unity.com/packages/vfx/shaders/psxeffects...

Godot shader example: https://github.com/MenacingMecha/godot-psx-style-demo

You can use modern modeling tools with self-imposed limits on model complexity and texture sizes. (Blender is even era-appropriate — its first public release was in 1998.)

Alternatively, see Crocotile3D, which approaches that era's aesthetic from a different angle of simplified tile-based modeling: http://www.crocotile3d.com/

I am using that exact Unity shader! :)
