Hm. Still at a loss. Do I have to save the game config to make it work? I would like to make a working configuration on the fly and only save it when it works. Also "User 1 Device Type" - I believe this should stay RetroPad? "User 1 Analog To Digital" - should I fiddle around with that? "User 1 Steering" is set to "Left Analog X" - which sounds reasonable, but does not work...
Maybe a stupid question, but have you installed the HDMI adapter that connects the Raspberry HDMI to the HDMI of the Game Hat? You probably had to remove it to install the Raspberry to the Game Hat, but after doing so you need to put it back!
install mk_arcade_joystick_rpi driver from ~/RetroPie-Setup/retropie_setup.sh
edit /etc/modprobe.d/mk_arcade_joystick_rpi.conf adding the following line :
options mk_arcade_joystick_rpi map=5 gpio=5,6,13,19,21,4,26,12,23,20,16,18
Additional to that i do not think the left thumb button (clicking on the analog pad) is working. It is not mentioned in the waveshares user manual as well. I will check if it is connected to an gpio input soon so it can be maybe mapped in the future.
Did you found further informations about this problem?
I'm also wondering, why there is no function on this button at all.
i think i see the problem and it might just be the refreshrates, when in emulationstation after boot,
but hitting a button before kodi loads,
Sorry for the larger second image, took it w/ my phone. so the problem might be its setting an invalid 30hz refreshrate that this display cannot handle.
ok, somethinsg dodgy... on loading Kodi, i'm whitescreen as per usual, But putty shows still
and it recovers after awhile, but the moment i press a button. pfft! Whitescreen.
ok lastnight which i forgot to post before passin out.. Reicast had teh same problem but it was setting an independent Render resolution, which was fixed by editing the emu.cfg this has me thinking either Kodi's setting a bad pixelclock/setting an independent resolution which the force options in config.txt dont do didly Squat.
The higher the speed, the better it displays, but anything above 27000000 f'd up the colors badly for me.
Definitely playable for anyone wanting to use this screen, but it still drops some frames, mainly during cinematics and stuff. Personally, Gonna try out a 5" HDMI screen, don't wanna compromise on the gaming experience too much.
