New page

{{NextRegister
|Number=$77
|Readable=No
|Writable=Yes
|ShortDesc=Same as {{NextRegNo|$37}} (write third byte of sprite-attributes), plus increments {{NextRegNo|$34}}
}}
Byte 3 is bitmapped:
{|class="wikitable"
! Bit !! Description
|-
| 4-7 || Palette offset, added to each palette index from pattern before drawing
|-
| 3 || Enable X mirror
|-
| 2 || Enable Y mirror
|-
| 1 || Enable rotation
|-
| 0 || MSB of X coordinate
|}
