This is a Video RGB Hack for the console Sega SG-1000 II (Mark 2).

The Sega 315-5066 Video Chip inside the Sega SG-1000 II (Mark 2) used in the latest version of the console uses two video output formats: NTSC Composite video (converted to RF), and RGB (not connected).

The RGB Video is the stuff from which all other formats are born. Once your RGB is tapped it can be easily converted to Component or S-video, giving stunning output far superior to what the Sega SG-1000 II natively offers (only RF).

There are several caveats, of course. The biggest is the quality of the RGB output – it’s not very bright, and will result in an image without much contrast, so you will probably need to add an amplifier. Even on monitors that display a very good image without the amp you’ll sometimes find the sync signal needs an amp to generate a stable image.

I have used the same RGB/Sync Amplifier used on the PC-Engine, components and the Original schematic are shown below.

Schematic:

Components:

• 4 x 2SC1815 (Transistor)
• 4 x 220 μF 16v (Electrolytic capacitor)
• 4 x 10 μF 16v (Electrolytic capacitor)
• 4 x 75 Ω (Resistor)
• 8 x 10 KΩ (Resistor)
• 1 x 300 Ω (Resistor)

The three photos below show the connection between the RGB Amplifier and the PCB of the Sega SG-1000 II.

Some new games (Cracked / Trained or Unrealeased) for Commodore 64 have been released from your favorites groups: Laxity, Genesis Project, Onslaught, The Hidden Farts, Antarctica, Underground Domain Inc, Dinasours and Really Proud Lamers.
