GBA and other Hand Helds

epicrean

When playing GBA or LYNX the images are too big so they are extremely pixilated, is there settings to change this? I know in other FE's you can add bezzels to clean up the look and feel. Thanks

i will totally sit here and let @Floob handle this
he posts a ton of videos, a lot of which will cover what you want: https://www.youtube.com/channel/UCdSu9Y0xAyY8V77vj6mQ-0g

In RetroArch you can apply an overlay that looks like the handheld. Or you can create your own bezel. It's fairly simple. You can also use shaders that do the same thing plus more, but you are limited to what you can find online unless you want to create a shader yourself :P

RetroArch Settings > Onscreen Overlay ?

To create your own, I think you can just add the png image (with transparency for the viewport) and then there's a tiny script file that calls the image. You can just look at the existing ones in notepad and change the png image being called.

You can also reduce the size of the image output by going to the settings menu in retroarch, then video, and then I think you need to specify a custom ratio and adjust the x y position as well as the size. Custom Viewport width, height, x, and y.

I did this for my handhelds and the result is pretty cool and much nicer on the eyes for a large monitor/TV. If I remember correctly, there is one other setting in video that I had to turn off... or on. Integer Scale...

Good luck! A bit tedious but necessary for a perfectionist :)

You can set custom viewports to reduce the size like this if you want:

Some videos shown at the top of that thread.

In terms of bezels, you can use overlays or shaders like this if that helps:

I installed the video manager and it does a great a job. However it only works on 1080P TV as you obviously know. My Pi is hooked it to a 720P tv typically, and sadly it fixes the consoles as far is scanlines and jaggys are concerned but it doesn't do anything for GB or other handhelds.

Also great job on the putting everything together.

There is a 720p section in the editor if you want to try that.

You could set some manual viewports for 720p.
So the native res on gb is 160x144, so you could simply use integer scaling

Or you could set some manual settings, so lets say you want it 4x as big, you could set

aspect_ratio_index = "22"
custom_viewport_width = "640"
custom_viewport_height = "576"

Or if that is too big, try 3x

aspect_ratio_index = "22"
custom_viewport_width = "480"
custom_viewport_height = "432"

@Floob
where do I go to set this

Floob

You could put it in the system specific retroarch.cfg
/opt/retropie/configs/gb/retroarch.cfg

You could do it manually or use the configuration editor
