RetroArch now has native support for the Bliss-Box 4-Play – a universal game pad adapter – in the latest nightly builds. This support will be included in the upcoming stable release (1.7.0). The new support includes a dependency on libusb, so anyone running the nightly builds should be sure to download an updated redist package to get the new lib.
(Editor’s note – RetroArch version 1.7.0 will be released later this week)
RetroArch has support for many adapters and the ability to add countless more, however, it does so by mapping per adapter. Similarly, the 4-Play also supports a large number of controllers but outputs them as one device. Previously, RetroArch could not map each game pad because of this. Fortunately, the 4-Play was designed with this in mind and has a built in API any project could take advantage of without the need of drivers. In this update of RetroArch each pad seen by the 4-Play is read in to RetroArch appending the pad type to the cfg file found during controller detection.
