@mitu The changes have to be made to/with the OMX player itself.

I guess that works too but I went into the actual Core config files, I cant remember the exact path, opt/retropie/configs.

@mitu That worked !!! 3 days that took and sleepless nights lol . Here's some code for people who may have the same problem

Edit Autostart.sh

emulationstation --resolution W H --windowed --screenoffset X Y

Thanks a lot !

Well i use a dualshock 4 controller so go into a game and once there i think is hotkey+Y or X (controls based on the EmulationStation setting)

@juicebag85 please fill out the information requested in https://retropie.org.uk/forum/topic/3/read-this-first

i ask because this behaviour (one core doing one overscan behaviour, another doing another) should not happen in standard retropie.

Yap, when i use Retroarch, i always choose "core provided" and any screen or device the resolution of the game is always OK.

@dankcushions said in Shader and ratio configuration issues:

@floxblah don't say 'any emulator'. give me an example. give me an example game. if it's not doing 4:3 what is it doing?

I use lr-fceumm emulator with duck tales (europe version). If i set 16:9 it will apply the 16:9 ratio and if i set 4:3 i have the game default ratio value (like the ratio value is unset).

ok but the default ratio will be 4:3 on almost all old games. some PAL (europe) versions will have borders but that won't be solved by changing your aspect ratio - they would have had borders on 4:3 tvs also.

fceumm will have options to change how it displays borders perhaps - select + X to get to the retroarch menu, then quick menu > core options. it will be the overscan options.

@jdrassa Thanks, it worked!
