Technical features

  • Lags. For real.
  • Uses only 32bit writes to $3C0000 to update VRAM and VRAM address instead of using word writes to $3C0002. Is one of the reason it lags so badly but it also means the code is interrupt safe. Raster interrupts writing to VRAM might conflict with VRAM writes in the main program. Also allows it to work properly on overclocked systems since the VRAM writing is so slow.
