Kakushin H3 System

The H3 System (stylized as H³ System) is a fanonical handheld gaming system.

Details
H3 is an abbreviation for "Holoscreen Hyper Handheld", an indication of its features. It features a miniature, high-resolution holo-projector that projects a screen that the system outputs the visuals to. Its specifications indicate high performance, with excellent processing speeds and powerful sound and graphical capabilities. The H3 is also optimized for online multiplayer gameplay on certain games.

Games are distributed on both physical media and digital downloads from the H3 HyperMart over the internet. Physical games are stored on a UMD-style disc based on the technology of 3D optical data storage, dubbed "3D-Op Discs". With the immensely high data capacities offered by 3D optical data storage technology, this meant that physical copies of H3 games would have more content on them than what was ever thought possible.

Trivia

 * The design of the H3 is based on the gamepad used in the arcade machine for Pokken Tournament, a photo of which is edited in Medibang Paint Pro with a Select button, holographic screen, and the controller cable was edited out.
