| 16 | DEDITHER_FILTER_ENABLE | Dedither Enable bit <br>1 {{=}} Dedither filter is enabled (normally used for 16-bit framebuffers; this may cause vertical banding if anti-aliasing is disabled [https://github.com/DragonMinded/libdragon/issues/159 as seen here]) <br>0 {{=}} Dedither filter is disabled (normally used for 32-bit color)
| 15-12 | PIXEL_ADVANCE[3:0] | Use <code>0b0011</code> for most effective behavior on N64. On the iQue Player a pixel advance of <code>0b0011</code> creates video glitches, applications typically use <code>0b0001</code> instead.
| 11 | KILL_WE | Diagnostics only, possibly kills VI DMA writes to line buffers making them safe to access via the test registers.
