Problem with NES overlays.

TMNTturtlguy

@beastmode try going into retroarch and changing the video aspect ratio to set by core and see if that works.

beastmode

@tmntturtlguy that gives me pretty much the same output as in the first 3 images. Black bars are on the left and bottom.

@beastmode What about setting a custom ratio? i would still set it to 4:3 but do it manually. Have you tried it with other roms in your NES folder? Could it be something weird within the rom itself?

beastmode

@tmntturtlguy It happens with pretty much all of the NES roms and most Sega Master Drive as well. I'll try setting a custom ratio. SNES, Genesis work perfectly.

TMNTturtlguy

@beastmode Well it is good to know that you have a few systems working correctly. I know that i have some roms that have slightly different aspect ratios than others, so that is why I was asking it it happened on all of your roms in that system. It sound like it is.

Just for the heck of it, have you tried to see what happens in lr-fceumm?

beastmode

@tmntturtlguy Same exact problem in lr-fceumm. I first had problems with that emulator before moving to lr-nestopia =).

I'd definitely ask you to post your RetroArch configurations for "all" and "NES" over pastebin if possible.

It is normal that some particular games seem to use different resolutions at times - on an original CRT things would either be cropped or sometimes have actual black borders. I'm not sure there will be a lot you can do in those cases.

That being said, we should probably at least attempt to minimize that effect here.

Send those over for us to take a closer look.

@pjft Okay. Here are the links.

@pjft @tmntturtlguy I was messing around with a few different overlay files and settings and have come up with different results. It does seem that some games have different aspect ratios or something.

Following images show these settings:

aspect ratio index = 22
custom_viewport_width = 1356
custom_viewport_height = 1012
custom_viewport_x = 281
custom_viewport_y = 22
video_scale = "5.000000"
video_scale_integer = "false"

Overlay File.

@beastmode It seems odd, but to me it almost looks like you might have to set the aspect ratio and location of each of your roms individually to get them centered. Hopefully @pjft can pull something from the config files you sent.

beastmode

@tmntturtlguy Indeed. If not, I'll just set them manually since there doesn't seem to be many. Much less than I originally thought. Do your NES roms glitch at all? Perhaps it's normal for them to do so, or maybe I have a bad rom file. In some of the games the characters will blink white, or disappear for a few milliseconds. Mega Man for example.

Sorry for the delay here.

I don't have a lot of experience with these kind of "border" overlays so maybe I haven't noticed this behavior in the past, even though it happens.

The top and lower borders are fine by me, but the left margin isn't right. It seems you're also using a shader - have you tried disabling the shader and seeing if it's affecting that in any way?

Reading your configs, and knowing that the NES resolution is 256x240, I'm wondering: in a 1920x1080p you shouldn't be able to fit a view screen of those dimensions with 5x video scale. Now, the fact that it's set to "integer" false, I'm not sure how it affects, but the actual scale is 4.21 for your values. Maybe change that and see if it helps in any way.

Have you tried setting it to "true" and "4" for scale, removing the width/height/x/y settings and seeing if the image in those games is effectively still off-center?

Sorry I can't help more here.

beastmode

@pjft Thanks. I'll give that a try.
