We’re celebrating the 25th anniversary of the Virtual Boy’s Japan launch with the final Virtual Boy Sacred Tech Scroll Version 1.0, the most accurate and up-to-date Virtual Boy hardware documentation. More than 7 and a half years have passed since the initial release, but the wait has been worth it! Here is Guy Perfect’s patch notes:

• So, so many corrections. The old one was good, but not great.
• New presentation: no longer a glorified text file.
• SVG diagrams have been added to visually depict hardware configurations.
• Now using official port and register names, even if they are proprietary.
• “Miscellaneous Hardware” broken into distinct sections.

Well this is some great news right here! 👍

Now all we need is another document that goes into various programming techniques that are applicable for VB (code, graphics, sound, etc.), so the system’s homebrew scene can have less-inferior games (and various demoscene stuff as well, which is something it’s extremely lacking in).

Great work! I’m already using it as a reference.

Very cool, that’s a lot of work. Great job!
