Set custom resolution

[taxilly]

Love ignores any width/height in conf.lua and framebuffer dimensions in /boot/config.txt, instead using the monitor resolution (1920x1080).

Yep, this is a limitation on the way SDL2 glues with the Dispmanx API and EGL.

I ended up using fbcp to copy over /dev/fb0 to /dev/fb1 and then adding;

# uncomment if hdmi display is not detected and composite is being output
hdmi_force_hotplug=1

# uncomment to force a specific HDMI mode (this will force VGA)
hdmi_group=2
hdmi_mode=87
hdmi_cvt=320 240 60 1 0 0 0

to /boot/config.txt which makes it use 320x240 resolution.

Great work on this btw 👍

Wonderful trick May, @Twentytwoo !
I hope to get the time soon enough to package it into pipaOS
so we get the latest kernel and Love2d versions through APT.
Thanks for sharing!
