Genesis Plus GX problem: Screen cropped to the left

Sorry if this has already been posted but I’m having a weird issue with Genesis Plus GX; the screen is cropped to the left.

Not sure if it’s related, but it only seems to happen with USA region roms. It doesn’t happen with the European Mega Man Wily Wars rom. Castlevania Bloodlines USA shifts from full screen for menus and stage intros, but goes back to cropped during gameplay.

I’m using the latest version of RetroArch and Genesis Plus GX.

can you post a screenshot?

This core handles overscan cropping in the core options, so that’s the first place I would suggest looking.

Sure. Here you go. I think I’m using the ntsc s-video shader, if that’s important.


Ah, I believe you’re using the ntsc video filter rather than shader, correct? If so, yes, that happens on cores other than NES or SNES (that’s part of why we recommend using shaders instead of filters whenever possible). Genplusgx also has its own modified NTSC filter in the core options that doesn’t have that issue.

So, your options are to: 1.) disable your video filter 2.) switch to ntsc shader instead 3.) use core’s built-in NTSC filter

Thank You! Disabling the filters did the trick!
