The RGB Master Class Season 3 Episode 12 RGB312 :: PC-Engine Interface Unit RGB Mod

The RGB Master Class is a technical show that focuses on various RGB modifications for classic video game consoles. In season 3, episode 12, titled RGB312 :: PC-Engine Interface Unit RGB Mod, the crew dives into the inner workings of the PC-Engine Interface Unit and explains how to modify it to output higher quality RGB video.

The episode begins with an overview of the PC-Engine Interface Unit and its various components. The crew explains that the Interface Unit was an accessory for the PC-Engine console that allowed it to play CD-ROM games. They also note that the Interface Unit has an RGB video output, but it only outputs a low-quality composite video signal.

The crew then demonstrates how to access the Interface Unit's circuit board and locate the RGB video output pins. They explain that the RGB signal is generated within the Interface Unit, but it is not properly separated from the composite video signal. Therefore, the RGB signal needs to be separated from the composite video signal using a circuit modification.

The crew then walks through the steps of modifying the circuit to separate the RGB signal. They explain that this involves cutting a trace on the circuit board, adding a capacitor to the RGB signal path, and soldering a new wire from the RGB output pin to the video encoder chip.

Once the modification is complete, the crew tests the Interface Unit's new RGB video output. They compare the modified RGB signal to the original composite video signal and note the significant improvement in color accuracy and sharpness.

Finally, the crew provides recommendations for anyone attempting this modification at home. They suggest using a desoldering tool to remove the necessary components and being careful not to damage any other components on the board. They also advise testing the modification thoroughly before reassembling the Interface Unit.

Overall, RGB312 :: PC-Engine Interface Unit RGB Mod is a comprehensive guide to modifying the PC-Engine Interface Unit for improved RGB video output. The episode provides clear instructions and practical advice for anyone interested in undertaking this modification for their own classic gaming setup.
