lr-opera cropping the image

[Nemed]

Hello everybody!
I wanted to try to emulate the 3do, and i've got a problem. The output image is not located in the middle of the screen but shifted to the lower side of the screen and the lower part of the image is completely cropped off (like on the screenshot). What's the problem and can it be fixed?

I use Raspberry Pi 4 B and the latest build of RetroPie (only installed it a couple of weeks ago). All emulators are set to use 320*240, aspect ratio "core provided", and RetroArch is set to use integer scaling.

Also, i don't know if it's connected, but now i can't open RetroArcg GUI from Emulationstation and access RetroArch settings. It just gives me black screen for couple of seconds and returns to Emulationstation. From in-game RetroArch menu opens just fine. I haven't manually changed any configs or something

Reinstalled RetroArch from binary and it didn't help. Still black screen instead of GUI

Reset the RetroArch configuration to RetroPie's default, you may have inadvertently changed them to something not supported on the Pi.
Remove the following files:

• /opt/retropie/configs/all/retroarch.cfg
• /opt/retropie/configs/3do/retroarch.cfg

then re-install the retroarch and lr-opera packages to re-generate the configs.

By the way the Gex exists and in the Playstation, just in case you want to play this game.

@mitu Thanks, that fixed RetroArch but no success with lr-opera. Tried to change res and aspect ratio settings with no result

@windg Yeah i know Gex is also on PSX but i also wanted to try some other 3do games like Space Hulk, Star Control 2 and Wing Commander remake
