big display of uqlx on rPi
Posted: Sun Feb 05, 2017 7:11 pm
Hi all !
As I am playing already for some rather long time with the Raspberry Pi (together with my QL and other emulators), I was curious to try to install Uqlx on it.
It worked almost without trouble, but I was disappointed with the size of the screen/characters.
But I found "my simple way" to better that : use of the xzoom command from a terminal window with following parameters :
xzoom -mag 2 3
dispays a nice 512x256 (basic) QL screen with the same (default) aspect ratio as my (original) 4x3 monitor.
So circles are circles, squares are squares, etc. and the characters are legible.
But I am still a little dissatisfied : the speed of the emulation cannot be adjusted (to the speed of the original QL), it is a lot faster (even on my 1st generation Raspberry Pi), and this is somehow problematic in two ways :
1/ The refreshing rate of the xzoom program cannot follow some animated displays.
2/ for some unknown reason, the screen editor of my Computer One Forth does not work properly : I already noticed that when using Qemulator at full speed on my PC (whereas it worked OK when Qemulator was let running at "the speed of an original QL" or even at "the speed of the Gold Card")
Here a screen shot of the result :
A/ the emulation (this window must be active for the keyboard and the mouse)
B/ the console on which I passed the command xzoom
C/ the zoomed image (width x 2 : heigth x 3)
Bye Paul
