Deep Dive into NES RGB Mods
1. Overview of the NESRGB Solution
The NESRGB mod, developed by Tim Worthington, represents a significant advancement in NES video enhancement. It is an internal PCB that replaces or works alongside the PPU (Picture Processing Unit), allowing for high-quality RGB and S-Video output without sacrificing original hardware integrity. Its design utilizes an Altera CPLD, enabling palette switching, in-game reset, and jitter reduction features.
2. Installation Process and Requirements
Installing the NESRGB involves removing the original PPU from your NES or Famicom and replacing it with the board, which mounts directly into the socket. The process requires a good soldering station, precise work, and knowledge of console circuitry. For top-loading models, compatible adapters are available. Some installations benefit from a separate voltage regulator to prevent overheating.
3. Technical Features and Benefits
The NESRGB offers multiple color palettes, allowing users to select different visual styles to suit their preference. The board ensures minimal latency, maintaining the original timing and responsiveness. It also supports a “dejitter” mode, improving compatibility with modern HDMI conversion devices, resulting in a crisper image.
4. Community and Support
The mod is widely supported by the retro gaming community. Several online resources provide detailed installation guides, troubleshooting tips, and video demonstrations. Professional installation services are also available for those uncomfortable with soldering, ensuring safe and reliable setup.
5. Cost and Availability
The latest 2022 version of NESRGB (version 4.0) is available from various suppliers, including etim.net.au, with prices generally around $100-$150 for the kit. Professional installation services, such as those offered by Voultar, add to the cost but guarantee quality work.
