Английская Википедия: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]
Technical specification
The HuC6270 generates a display signal composed of background (with x y scrolling) and sprites. It uses external VRAM via a 16-bit address bus. It can display up to 64 sprites on screen, with a maximum of 16 sprites per horizontal scan line.[5]
Uses
The HuC6270 was used in consoles PC Engine and PC engine SuperGrafx consoles. Additionally, the VDC was used in two arcade games.[6] 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 video color encoder,[7] that is in the PC Engine.[8] 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.
