Mike Dailly | ZX Spectrum Next RayCasting Engine - Full Layer 2 rendering @MikeDailly | Uploaded January 2020 | Updated October 2024, 1 day ago.
Current state......

I have updated the rendering to use Layer 2 (256x192) instead of the lowres more (128x96). I have added some auto generated rendering code to help speed things up enough to be able to fill 4 times the screen area.

Still some optimisations to do

Recorded on the actual hardware.
