Hudson Soft HuC6270

HuC6270 is a video display controller (VDC) developed by Hudson Soft and manufactured for Hudson Soft by Seiko Epson.[1][2] The VDC was used in the PC Engine game console produced by NEC Corporation, and the upgraded PC Engine SuperGrafx.[3][4]

Besides use in consoles, the VDC was used in two arcade games.[5] 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 known as the video color encoder that is in the PC Engine.[6] 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.
