How to load Retropie games in full screen with no black parts...

Is EmulationStation showing a border as well? If not, then go into RetroArch and adjust the aspect ratio if it's not to your liking. Gameboy Advance was 240 × 160 pixels (3:2 aspect ratio), not 4:3.

@obsidianspider Is it because the resolution of the screen is 320 by 240 and the resolution of the GBA is 240 by 160, because of the difference in resolution??

So that means I cannot play in full screen... right?

Is there a border when in EmulationStation, or only in games?

if you open up:
/opt/retropie/configs/all/retroarch.cfg and add this to the bottom and save, it will fix it in all retroarch emulators:

custom_viewport_x = 320
custom_viewport_y = 240
aspect_ratio_index = 22

@obsidianspider The problems are only happening in the games.

Emulationstation is fine. However, the text commands are extremely small...

@dhlee20 please read my post above

@edmaul69 When I entered these commands in the very bottom of the document and rebooted, now the game doesn't load after the loading commands at the screen...

I'm doing the PiGRRL 2 by Ruiz Brothers in Adafruit. Is it okay to apply in the PiGRRL 2 specialized image?

@dhlee20 did you do this in the retroarch.cfg? If the screen is 320x240 not sure what the problem is. I havent messed around with the small screens even though i have two of them but never installed them yet. Maybe the aspect ratio index is different??

Also can switch aspect ratio in the configuration editor. Saves manually editing files etc.

I bought a 2.8 inch 320x240 PiTFT display for the PiGRRL 2 project from Adafruit.

When I load GBA games in Retropie, there are about 5mm of distance from the end of the screen in both sides.

Can you guys tell me how to load the game in full screen? (whole screen with no black parts)

<config.txt settings>

#framebuffer_width=320
#framebuffer_height=240

#sdtv_mode=2
#sdtv_aspect=3

Remove the # symbol from config.txt in these lines:

#framebuffer_width=320
#framebuffer_height=240

See if that helps.
