PC-Engine DUO : RGB mod and jailbars fix

Thu, 03 Mar 2022 12:52:39 +0000

The video output of the original PC Engine DUO is composite only. Fortunately, the quality of its output is really good comparing to other consoles from the late 80’ / begining of 90’. But the signal is NTSC-J and if your display is not compatible, the picture will be in grey instead of colors. And that is the case of my old european CRT TV (a Grundig one). So I purchased an RGB kit from otakus-store and modded my DUO. The result is a nice and very sharp picture, but like many others I also had to fix the so called “jailbars” problem after this mod.
