Bliss-Box : 4-Play - One Adapter for Many Controllers

Feature List

    Full Emulation  - A huge variety of controllers are fully supported out of the box. Even more complex features like the PS2's pressure sensitive buttons are already implemented. For a very detailed list of what is currently supported, see our full Compatibility List. This list is periodically updated and added to as we gain more insight from our beta testers and continue to work on the firmware.
    Multiplatform - Use your 4-Play on almost any modern operating system. The 4-Play works on Windows, OSX, Linux, Raspberry Pi, Android, and the PS3.
    Out of the Box Ready - The 4-Play needs no software drivers to be installed by the user. Simply plug the 4-Play in and set your emulator or game to use the 4-Play's controller inputs.
    Auto Pause - When a controller is unplugged, the 4-Play automatically presses the start button, pausing the game where possible.
    Auto Pause Detection (Hot Swapping) - The auto pause detection feature makes it easy to switch between controllers mid-game. The 4-Play will auto pause your game while you switch, and you can continue playing when you're ready. The 4-Play automatically detects the new controller.
    Global Button Mapping - The 4-Play's internal button mapping is set up so that buttons on different controllers match each other's layout as exactly as possible. This makes Hot Swapping easier and more intuitive. Of course you can remap the inputs any way you like in your game or emulator. Here are the details on our global mappings.
    Force Feedback - Controller rumble works on a wide variety of controllers. The currently supported force feedback controllers are the Nintendo 64, GameCube, PlayStation 1, PlayStation 2, and Dreamcast. Note: To improve this feature we recommend you plug the power adapter into the 4-Play. This adapter is included in the Mega Set, but is sold separately for other sets since it is not required to use the 4-Play.
    UDLR Mode (D-Pad Only Mode) - This puts the 4-Play into a D-Pad only mode which allows the player to use the D-Pad to play a game which requires the analog stick. To activate this mode simply hold Left Shoulder, Right Shoulder, and (Pause or Start) Button. This causes the 4-Play to interpret the D-Pad inputs to their corresponding analog stick inputs. You can switch this mode off with the same button combo. This allows you to hot swap to non-analog controllers while playing an analog game. This mode is also controller port specific, so Player 1 on the 4-Play can use this mode while other players are in whatever mode they choose.
    Upgrades - The 4-Play can be easily updated via USB with a firmware file which can be downloaded from our website. This allows new features and controllers to be added via a simple firmware upgrade. Each 4-Play controller port has its own firmware chip so multiple firmware versions can be used if desired.
    Developer API - The 4-Play will have an API with which emulator developers can communicate directly with the 4-Play and swap data back and forth. This will allow developers to natively support some of the more advanced features of the 4-Play. For example, developers could use this API to see exactly which controllers are currently connected to the 4-Play for display on the screen or automatic custom remapping. They could natively support saving to the controller's memory card, and even write images to the Dreamcast controller's LCD screen. Support for the GameCube's Gameboy Advanced Link could be added. The possibilities are endless.
