@curtmack @foone ...i thought most of these were well known
the only ones we don't know are "mode 5 palettes", "palettes aren't palettes", and "the brown circuit"--and would be interested in seeing more information on those

@Hearth @foone - Mode 5 is an undocumented mode that disables the color burst while also combining the two mode 4 palettes (cyan/red/white, instead of green/red/yellow or cyan/magenta/white). It also respects the palette intensity bit, so two palettes total. - Graphics in mode 4 get their color because the two per-pixel bits and the two palette select bits each correspond to one of the RGBI bits for that pixel. So they aren't "palettes" in the traditional sense.
