Welcome to Wataroo

Wataroo is a Watara SuperVision emulator. It was originally written after I lost a bet with Brandon Cobb. As with a genuine SuperVision, the best way to use this software is not at all.

As of writing Wataroo is closed source and only available for Microsoft Windows.

This program is intended as a development tool for and preservation of the SuperVision architecture. While it can be used to run commercial software I will neither assist nor prevent users from doing so. You are on your own.

More information can be found in the included help file. If you're still craving juicy SuperVision trivia, check out SuperVision : Handheld of the Less Fortunate a feature of Diskman Presents.

My reverse engineering notes are available in EQU_WATARA.asm.
