retropie questions

Hi!


I'm trying to configure mupen64plus-glice2rice plugin on my retropie
using last version on a pi4b. So far the image quality and smoothness of
play is well above all other mupen64 plugins. But I cannot get it to run
at a 4:3 ratio at a full screen height (1080)... it always stretch to
16:9 even if I set parameter to stay in 4:3 ratio... If I choose a
640x480 in the runcommand  it would be 4:3 but a very small image in the
middle of the screen... All other mupen64 plugins are ok in 4:3... If
the mupen64plus-glice2rice cannot be used in 4*3, is there a way to tune
the mupen64plus-glideN64highres plugin to run as smooth as the rice and
as pretty?


Thanks and have a nice day
