I recently purchased a prototype of Super SWIV. It turned out to be an almost final prototype of the Japanese version of the game. I wrote up a short article for the release.

This is the source code to get the Super NES mouse working. It includes a diagnostic program to test the mouse. Many thanks to Frank Cifaldi and The Video Game History Foundation for preserving this, and Luigiblood for assembling the binaries.

I'm have written an article about an official DSP1 demo that was created by Nintendo. The source code was originally written in mid-1992, and the comments translated to English in early 1993. Many thanks to Frank Cifaldi and The Video Game History Foundation for preserving this, and Luigiblood for assembling the binaries.

I have received nine PCB boards that were not in my last update, bringing the total to 179. These include some prototype boards, and some additional variants. Thanks to Matthew Callis, phonymike, gornway, Zakaria Mahdaoui, marvelus10 and Markfrizb for the contributions.

Today, I have uploaded a major update on the documentation of PCB boards. This is the second step in my long term plan to make SNES Central more database centric. With this update, there are a total of 170 PCB types documented, with more complete information than what was previously on the pages. This is the first of two updates, there will be another one soon with more prototype boards.

Lately, a number of prototypes, authenticated by Wata, have shown up in my Ebay searches. However, it would be charitable to call these "prototypes", and I have written up an article to show why I do not think they should be in the business of authenticating prototypes, because they do not know what they are doing.
