@mitu Good suggestion, but still no luck. I even verified the setting in the Retroarch Menu-Settings-User Interface, and although the setting shows active, it does not seem to have helped. (The behavior is unchanged)

I found a problem and it is now solved. I ran lr-dosbox-pure in verbose mode and in log /dev/shm/runcommand.log I found error:

eglCreateImageKHR: failed to create image for buffer

After searching for a while on the Internet, I found a tip for editing the file /boot/config.txt and add the line:

gpu_mem = 256

After this the display no longer flashes (flickering) and everything works fine.

I still have to figure out how to emulate a mouse like a touchpad...

@mitu Everything that is mapped to my controller works if Game Focus is turned off. Problem is now with 1.9.4. the keyboard doesn't work until Game Focus is turned on. Once Game Focus is on, I loose all the mappings, I can't even open the Retroarch menu. What was the need for the change. Before this version, I never saw this happen.

It doesn't effect any games that do not use a keyboard until you get to Amiga, A800, AtariST and DOSbox-pure.

I don't know a way around this without plugging in a true USB keyboard that has a scroll-lock key. My BT unit doesn't have one. I opened the retroarch.cfg and tried to remap the Game Focus key to another key, but it keeps automatically reverting back to scroll-lock as the entry.

I've deleted Retroarch and reloaded it by source thinking maybe some file is still hanging around from a previous build, but it didn't change anything.

I'm not sure what else to do with this other than buy a new, portable BT keyboard that has a scroll-lock key on it.

Update....nevermind... I found this on reddit and see there is a way to reassign the on/off toggle. I set mine to page-up key. All good.

Works fine. Now I can toggle it on and off and use both the hotkeys and keyboard as needed. Works great.

Thanks again.

Hi there, first day testing dosbox-pure and looks very promising! One question (or bug reporting) regarding controller: in the retroarch menu, settings, hotkey binds, I have put for on-screen-keyb the key 1 (by default 2 is for the menu and 3 is for the restart), but when I use the combination hotkey+1 the os-keyb does not appear. My gamepad doesn't have L3 so I need a solution like that - thanks and keep up the great work!
