drastic is not a libretro core, so the file you added doesn't have any effect on the emulator. I see that drastic has a 'Screen orientation' option, but it doesn't seem to add any rotation - maybe works only on Android (?).
@shylock since more or less every videogame supported by retropie is in 4:3, you're always going to get borders on the top and bottom (rather than the left and right that you would get with a 16:9 display. integer scaling won't make a difference.
with vertical MAME games it would be a nice fit, though: smaller borders on left and right than (un-rotated) 4:3 or 16:9 screens.
you'd also probably need to get a custom emulationstation theme done, unless someone has already done a square one, otherwise it's going to a look a little funky it think.
Please add more info about your system, as detailed in https://retropie.org.uk/forum/topic/3/read-this-first.
Changes in RetroArch's configuration are not saved automatically, you need to either save a configuration override (for the Core used or for the Game) or - if you want to change an option globally - use the RetroArch entry in the RetroPie system and save explicitly the configuration.
so its official, i'm quiting this build.
looking forward to future projects and hoping a pi zero 2 will come along.
i just wanted to take the time to thank everyone here for the effort to make all these projects possible for us, you are doing a great job and i am very greatfull for that.
already have a pi4 at at hand with 4gb and waiting for dreamcast emulation as i see the promising flycast core inplimentation,thats my all time favorite console looking to be very well emulated.
so big thanks to all and let me know if i can donate without paypal, cause i really don't like paypal.
You can connect a second display only over the GPIO - something similar to this setup should get your 2 independent displays - one for normal gaming via HDMI and a 2nd one over the connected over SPI (GPIO pins).
The 2nd display can be used for showing the images (via fbi) or even videos (via omxplayer).
Switched back to VGA and uncommented 'hdmi_force_hotplug=1' and it seems to be working great! We will see how the sound is when I hook up the amp and speakers, thanks everyone for the advice! Really appreciate it!
