Recently got interested in trying to find a way to use Borders for GBA games utilizing RetroArch-Wii.
I think I've come up with a decent solution... just a warning... it won't be pretty.

First, set your Wii and TV/Monitor to 4:3 Aspect Ratio. You can utilize 16:9 but I personally don't use these settings in neither because it's anamorphic 16:9 and not true 16:9.
Then you'll need to get RetroArch for Wii. Get your preferred GBA core from any build.
Personally, I utilize 1.9.0 - mGBA (0.8.3), where 1.9.0 stands for the version of RetroArch I grabbed the core from, and the rest is basic core information. Just an important warning about this, new versions of RetroArch has crackling sound in new cores, and old cores are not compatible with Overlays. Play it safe and use the version I use.

Once you get your GBA core, open up RetroArch in your Wii and load a GBA game with the core of your preference.
Press RESET to open the QUICK MENU.
Go to MAIN MENU -> Settings -> Video -> Scaling and make the following changes:

SCALING​
NameSetting
Integer ScaleOFF
Aspect RatioCustom
Custom Aspect Ratio X Pos.110
Custom Aspect Ratio Y Pos.70
Custom Aspect Ratio Width480
Custom Aspect Ratio Height320
Set VI Screen Width640
Crop Overscan (Reload)OFF
Overscan Correction (top)0
Overscan Correction (Bottom)0

After you made these changes, simply press RESET on your Wii to close the MENU, or press B all the way to the MAIN MENU -> Quick Menu -> Resume.
You should see a somewhat centered smaller GBA game screen. Here's a small video showing the difference between CUSTOM Scaling and Core Provided Scaling:


After you've done these steps, open the QUICK MENU with RESET.
Go to On-Screen Overlay and make the following changes:

ON-SCREEN OVERLAY​
NameSetting
Display OverlayON
Hide Overlay in MenuON
Auto-Rotate OverlayOFF
Overlay Preset*Choose your Overlay*
Overlay Opacity1.00
Overlay Scale1.60


Once you've made your changes, simply navigate to your Overlays folder, and pick one from the "GBA" folder I've attached in this thread.

By following these simple steps, you'll be able to play any game in RetroArch with GBA borders around them!

In the attached ZIP file, you'll find 8 "different" Overlays for you to enjoy...
I'm planning to do ARCADE Bezels, but that's going to take a while and it's very likely that I won't do them anyways... It's just an idea I have for now.

Hope you guys try these out to bring back a bit of nostalgia to your Retro Gaming Sessions!
