Yeti3D is a pure PSP port of Yeti3D that is not dependent on SDL, it contains the source and compiled eboot. It was later renamed to Yeti-PSP (according to developer the updated version had not been realeased).

Features

  • The current viewport is 120x80 pixels, 15bit.
  • All textures are 64x64 8bit.
  • Textures are converted to 15bit via a pre-calculated lighting LUT.
  • Polygons can be any convex shape. Only squares are currently used.
  • Each vertex is described as X, Y, Z, U, V and brightness.
  • The renderer uses 24:8 fixed point maths.
  • Polygons are clipped in 3D space using 45 degree planes. Distance to plane calculations therefore use only additions and subtractions.
  • Polygon edges are clipped using one divide and 6 multiplies.
  • 4 clipping planes are used. No front plane is required. No back plane is used.
  • No per-span clipping is used. Fixed point errors are hidden offscreen.

Installation

It comes with 2 versions:

  • EBOOT.PBP - Regular version that runs smoothly.
  • FAST_EBOOT.PBP - Essentially the same but without the restrictions of sceDisplayWaitVblankStart.
