Added splash screens during installation.
Fixed loadwait option in OSD.
Added “classicaudio” to osd.cfg. This enabled old PCM(1 device, 2 index) audio devices. We now default to the new Headphones/HDMI 2 audio device system.
SD card files are stored in SDInstall. See readme.txt inside SDInstall for instructions on manually installing the SD card files.
For Windows users, the ExperimentalPiUtility can be used for all necessary steps. Installing the Windows USB driver, copying files to the SD card and editing the cmdline.txt automatically and updating the Piboy firmware over USB.
For non-Windows users or for those who’d like to use the commandline in Windows, there is a very simple python based firmware update utility(loader.py). It requires pyserial be installed and the only argument is the device port(eg: /dev/ttyACM0 for Linux/RPi or COM4 for Windows).
