Impossible to change to 4:3 ratio ! ARGH!"#€

[fiddan]

Hello!
I am new to Retropie so all this is alien for me.
My problem is that i cant change my resolution for my snes games i have an 720p widescreen computer monitor.

I have tried to push down X at start up when i load games.
“1 Select default video mode for emulator/port”
I have tried to change to almost every DTM-xx whit 4:3 ratio.
Also the ntcs and pal 4:3 options at the bottom.

/opt/RetroPie/configs/all/retroarch.cfg
I have changed to this

video_aspect_ratio = 1.33
#1.333333 (4:3) Traditional SDTV
#1.56 (14:9) 4:3/16:9 Compromise aspect ratio
#1.6667 (5:3 Super 16mm)
#1.77 (16:9) HDTV US standard 
#1.78 (16:9) HDTV US standard alternate
#1.6 (16:10) Common computer screen ratio
#1.6667 (5:3) Common European widescreen standard
#1.85 Common US widescreen cinema
#2.39 Current widescreen cinema alternate
#2.40 Current widescreen cinema alternate

And the /opt/retropie/configs/snes

# All settings made here will override the global settings for the current emulator core

video_shader = /opt/retropie/emulators/retroarch/shader/snes_phosphor.glslp
video_shader_enable = false
video_smooth = false
video_aspect_ratio = 1.33
#1.333333 (4:3) Traditional SDTV
#1.56 (14:9) 4:3/16:9 Compromise aspect ratio
#1.6667 (5:3 Super 16mm)
#1.77 (16:9) HDTV US standard 
#1.78 (16:9) HDTV US standard alternate
#1.6 (16:10) Common computer screen ratio
#1.6667 (5:3) Common European widescreen standard
#1.85 Common US widescreen cinema
#2.39 Current widescreen cinema alternate
#2.40 Current widescreen cinema alternate
input_enable_hotkey = nul
aspect_ratio_index = "6"
video_scale_integer = true
rgui_show_start_screen = false

I have been working at this problem for many days right now and i have been done many changes in different files, i have done almost every tip from my google searches :/

One more problem is that form some guides from google i my folder index do not look like others sometime. i have installed the RetroPie SD-card Image, but i don’t know the version number, only Emulationstation v2.0.0-rc1.

Thanx for the help!

You have to choose your monitor’s native resolution as the video output resolution. Retroarch render resolution should match this. The native res is the maximum res your display is capable of.

You cannot get a perfect 4:3 aspect ratio without scaling artifacts using a fixed-pixel display. Well, there are some exceptions, but SNES isn’t one of them. Your best bet is to use 5x integer scaling on the Y axis and set the X axis accordingly. This will result in a slightly wider than 4:3 aspect with the top and bottom cropped off, but with the original pixel aspect preserved. See “how to get perfect video scaling”

It is highly recommended that you not set video output to anything other than your native res, as this will cause input lag and scaling problems.

EDIT : I see you are using a 720p display. In that case, just follow the instructions for setting integer scale. You can usually get close to a 4:3 aspect ratio. I think 4×3 integer scale gets you close to a 4:3 aspect ratio with NES for example.
