No, not today ;
for Xmas I bought myself a Pi400 computer, but playing with it for a while, I decided no longer to read MagPi on my computer, but to subscribe to the paper issues for one year.
Surprise : with this subscription, I received a free PiZero (last model : monocore, 1Ghz, integral Wifi and BlueTooth). I reused the Raspian SD that I had in my old RaspberryPi (also monocore, only 700Mhz thus slightly slower, and no integral Wifi, Blurtotth).
And as i had installed uQLx, this PiZero became my tiniest QL. Indeed, the screen of the emulation was small too,
but there are several cures :
1/ use the option "double pixel" in the configuration menu ; the pixels are two times larger, but still square : to get a correct aspect ratio, you have to set your TV to 4/3 instead of 16/9 full screen.
2/ use the command " xzoom -mag 2 3 " ; because of the parameters 2 3 the correct aspect ratio shows on the 16/9 screen in the zoomed window.
