XenoGC GameCube modchip installation

William Quade on March 31, 2018

I’ve been selling XenoGC modchips for the Nintendo GameCube on my eBay store. I thought I’d write a guide on how to install the XenoGC.

The XenoGC is a popular modchip that allows you to do many things. It can directly boot both game backups and genuine games from any region. It will work on all GameCube models. The chip is fairly easy to install since it only requires soldering six points, no wires required.

The XenoGC source code was released in 2011, meaning if you wanted to you could make your own with an ATmega8L. I may end up doing this in the future, and writing a post about it. Right now you can find XenoGC chips available from places like eBay. [Read More]

Nintendo 64 (N64) RGB SCART video output using THS7374 amp

William Quade on January 28, 2018

I recently bought an Open Source Scan Converter, or OSSC, primarily to make PlayStation 1 games look better on my display. After seeing how well RGB looked on the PS1, I had to try it on other consoles.

I already owned a Nintendo 64 and was using S-Video for video output, which is better than composite, but not great. When I installed the THS7374 amplifier into my SNES Jr. I bought an extra amplifier so I could do the same mod to my Nintendo 64. That’s what this guide covers, getting RGB SCART video output from the Nintendo 64. [Read More]

SNES Jr. (SNS-101) RGB SCART video output using THS7374 amp

William Quade on January 27, 2018

I recently bought an Open Source Scan Converter, or OSSC, primarily to make PlayStation 1 games look better on my display. After seeing how well RGB looked on the PS1, I had to try it on other consoles.

I ended up buying an SNES Jr. (SNS-101) for the improved visual quality from the 1-CHIP board design. The biggest downside of the original SNES Mini is that it doesn’t output RGB SCART out of the box, so I installed an THS7374 based amplifier, which is what this guide covers.

What is RGB video?

In the United States most older video game consoles used either RF or composite video (coaxial cable like what you get cable TV out of, or the yellow/red/white cables) to output video onto a TV. These video output options are passable on a CRT television, but on a digital HDTV it can look quite bad. [Read More]

PM-41 (2) PSone MM3 modchip installation (PIC12F629)

William Quade on September 26, 2017

In April I wrote a post about installing an MM3 modchip into my PSone with the original PM-41 board. I have also written a post about installing an MM3 modchip into my SCPH-7501 with the PU-22 board. This is a similar post, but covering the final revision of the PS1, the PM-41 (2) board.

Before I begin I’ll give you a little bit of background information. I purchased eleven PSone consoles on eBay with the goal of installing MM3 modchips, and reselling them for a decent profit. Out of the eleven consoles eight were the older PM-41 board design, and three were the newer PM-41 (2) board. [Read More]

September update 2017

William Quade on September 1, 2017

Last month I wrote an update for August 2017 where I summarized the posts I wrote in July, and listed some possible posts that could be published in August. This is a similar post, but for September 2017. I’ll talk about my plans for the month.

August post summary

Last month I wrote four posts, not including the update post. Topics included modchip installation on another PlayStation 1, and a more detailed guide on how to install custom firmware onto a PS3 slim using a Teensy. I also wrote my first electronics posts covering a DIY bench power supply, and how to make PCB schematics. [Read More]
