First of all thank you for Retropie – I’m only starting out with this software but already I am impressed with how easy it has been to get things setup. Currently I’m only testing out the PSX emulator on the 2.3 SD-card image. One issue I haven’t been able to figure out yet, despite trawling the forums and reading through the documentation is display scaling.
Out of the box, RetroPie displays games stretched to fit the full screen. I’m not sure if this is a limitation of the RPi hardware or a configuration option I’m missing in RetroPie but the options I’ve tried toggling in the config files don’t seem to have an effect. My goal is to display the games in a 4:3 format taking up the full vertical height of the screen with black bars on each side of the horizontal.
Has anyone had any luck with this? I am connecting to a 720p TV over HDMI if that is any help – please let me know if you require any config dumps, although I believe I am running things mostly stock.
