A Minecraft shader that recreates PS1 visuals. Features:
- Ordered dithering
- 5-bit per-channel color quantization
- Gouraud shading with banded light levels
- Vertex snapping
- Affine texture mapping
- Fog (scary)
Most of these are configurable via the shader settings! Only thoroughly tested with Iris on 1.21.11 (works on older versions too, please report bugs). Works with DH & Voxy.
