TL NES RGB mod done...

TL (Top Loading) NES or NES2..whatever people are calling it nowadays. Anyway, I finished installing the NESRGB in it.

It's been a while since I modded my TL NES. I did a simple A/V mod using a PNP transistor and some other components and tapping the video signal from the PPU. It worked, but not without it's own problem. Biggest one being jailbars on the video signal. So, NESRGB gets ordered and installed.

It's no different from the AV Fami installation. There's just one caveat: audio. What's not mentioned is that audio will need to be tapped directly from the CPU. It doesn't need to be tapped on the AV Fami since audio is already there on the connector.

Audio tapped on pin 1 and 2 on the CPU. Pin 1 needs to connect to the "A" pad on the NESRGB, pin 2 to the "B" pad. It does mention this part in the NESRGB pinout PDF, though...yeah, I missed that the first time, whatever. Audio can then be output to, in my case, the multiout connector from the "O" pad on the NESRGB.


Final installation. I ordered this piece from Laserbear.net. It was a complete kit (Adapter connector, multiout PCB, and the 3D printed back panel). I ordered it in this "Famicom Red" color; I really like the color offset. Plus it gives it some color from it's roots with the OG Famicom.

It's nice to knock out some of these mods that I've been meaning to do for a long time now. I did have an opportunity to get an Hi-Def NES kit (HDMI NES), but I skipped on it...I may regret that, but there's word that there's more being made with newer components. I have my old front loading NES that could benefit from that mod.

Next things I may be working on is my Coleco Gemini, Atari 2600 Jr., OG Famicom, or Game Gear. Stay tuned!
