Virtual Virtual Boy (VVB) is an emulator designed for the Virtual Boy 3D console. This Android app allows users to play Virtual Boy games on their smartphones using a pair of cheap Anaglyph 3D glasses or Google Cardboard.

One of the key features of VVB is its compatibility with various 3D viewing options. Users can choose to use Anaglyph 3D glasses, which are affordable and widely available, or they can opt for the more immersive experience of using Google Cardboard. This flexibility allows players to enjoy Virtual Boy games with a sense of depth and immersion.

For those interested in exploring beyond the original library of Virtual Boy games, VVB also supports homebrew games. These free games can be found on the Planet Virtual Boy website, and one such example is Red Square, developed by Kresna and Nyrator.

It's worth noting that VVB is not affiliated with Nintendo or Virtual Boy in any way, as stated in the disclaimer. The emulator is a standalone application created by Simon Gellis, providing Virtual Boy enthusiasts with an opportunity to experience the console's games on their Android devices.

Overall, Virtual Virtual Boy offers Virtual Boy fans a way to relive the console's unique gaming experience on their Android devices. Whether using Anaglyph 3D glasses or Google Cardboard, users can enjoy Virtual Boy games with enhanced depth and immersion.
