These boards allow you to convert an RGB modified TurboDuo, PC Engine Duo/R/RX, CoreGrafx, or SuperGrafx to use HDRetrovision component cables.

All it requires is a DIN8 connector and cable wired to the inputs on the board. Along with a 9pin miniDIN PCB mount connector for the output. I also have a 3d printable enclosure available on thingiverse.

Please note, these have been tested with the Mickcris amp and the Voultar v.69 Duo amp. I have not done testing with any other RGB amps and cannot be held responsible for any damage that may occur by your using these boards.

2 Channel sound amplifier for the Neo Geo MVS MV-1Fx series boards. This amplifier will combine the 3 audio channels into 2 audio channels. This board is ideal for low profile installations by using only surface mount components.

This is based on the design by ArcadeTV.

This design expects you to have a properly attenuated cable.

This design can be used by either removing the RF Modulator from your SMS/MD/Genesis or by just using 3M tape and securing it elsewhere.

Resistor values for all models are on the rear silk screen.

This is based on the original design schematic by ArcadeTV. This design expects you to have a properly attenuated cable.

Resistor values for all models are on the rear silk screen. Vias are masked so no isolation should be required. As of right now, this board is un-tested but since it’s based on my other board, it should be in working order.

This is a cheap and professional solution for connecting signals to a s-video jack or 4 pin mini-DIN jack.

All ground signals are connected through the ground plane on this board. If you require individual ground signals, modify this board to have individual traces.
