@bobharris Hi. first, I updated to 4.4 and played around with retroarch shader options. Now, I use crt-pi or waterfall shader with megadrive emulator and I'm satisfied with it. I tried setup a retroarch hotkey [SELECT + DPAD up / down] with my PS3 Dualshock Controller for shader next and shader prev option but it doesnt work. Does anyone know the right hotswitch entry for retroarch.conf
pi@raspberrypi:/opt/retropie/configs/megadrive $ grep input_shader_next *
retroarch.cfg:input_shader_next = "m"
retroarch.cfg:input_shader_next_btn = "0"
retroarch.cfg:input_shader_next_axis = "nul"
retroarch.cfg:input_shader_next_mbtn = "nul"
