That other thread reminded me to ask a few questions about ql emulation on Zesarux.
How to load standard ql files without any extension, from a media/ql folder ?
For example, I would like to load ql chess, but I dont know how to do it.
Also how to load mdv image?
I tried four mdv test images from the my_soft/ql folder, but always report an error in the file size.

MDV support is not working yet. You can only load files that are real files on your pc, for example, the ones on folder extras/media/ql/spacepods/

Watch this example:

OK, I tried but I have a little problem.
I selected the appropriate folder (e.g. Psion Chess), but I got the message "At line 90 channel not open".
Still, I tried load mdv1_BOOT, but I couldnt find a way to type underline character on the keyboard.
Usual Shift + ? not working...

Obviously there is a problem in the basic Boot file (line 90), but I dont know why, becouse the same file is normally loaded into the Q-Emulator.
In the meantime, I managed to start the program by deleting line 90, and select Psion chess folder twice, for mdv1 and for flp1.
However, after reaching the main screen, the game freezes.
Where am I wrong?

btw, spacepods from your example video, loads normally...

In the meantime, I managed to install v6.1 RC on Raspbian under RetroPie, but its very slow on my Pi 2, overclocked to 1.1 Ghz.
Spectrum emulation works at full speed only with a reduced core option and real video off, without frame skipping of course.
More demanding emulators like QL, work visibly slower.
I noticed a general slowdown on Pi 2, since v5.0, but then I didnt care too much, because I used v4.0, which worked much faster.
Now I wanted to try v6.1, with all the new features, but I find it quite demanding on my Pi 2.
I dont know how fast is on Pi 3B, but I hope someone will test on the new 3B+, which can work at 1.6 Ghz.
I also tested the ZX81 emulation, which doesnt have a speed issues, but some tricky demos are still not working properly, just like a few years ago.
Is there any way to speed up emulation, at least to use real video option, without frame skipping?

Ql emulation is in beta stage so don’t expect it to work perfect
Basic loading produces some random errors on some sentences, I know it but I haven’t found the reason why
About keyboard, I suppose you use the sdl driver on retropie. It seems symbol keys are not working, it’s the same issue as the windows version. On Linux you can use the fbdev or x11 driver which does work
About the cpu use... well it’s not the same emulating a z80 or a Motorola 68008, if it’s slow for you, try the reduced core
Cheers
