After almost six months of on-and-off development, I finally got v0.7 of BeagleSNES out the door. It includes all of the new emulators and is the first version to support OpenGL ES on the BeagleBone Black for hardware scaling to all sorts of HDMI and DVI display resolutions. You can download the pre-built microSD card image and source code at beaglesnes.org, so go get it and give it a try!
