Hudson Soft HuC6270

[3][4] The HuC6270 generates a display signal composed a 9-bit stream pixel data with a color and palette indexes,[5] and indication of whether the pixel corresponds to background (with x y scrolling) or sprites.

[3][4][7] Additionally, the VDC was used in arcade games:[7] The arcade version of Bloody Wolf ran on a custom version of the PC Engine.

The arcade hardware is missing the second 16-bit graphic chip, the HuC6260 (鉄観音 - "TETSU") video color encoder,[8][9] that is in the PC Engine.

[10] This means the VDC directly accesses palette RAM and builds out the display signals/timing.

A rare Capcom quiz-type arcade game also ran on a modified version of the SuperGrafx hardware, which used two VDCs.
