I was trying to set up some vertical uborder presets but to make it work I have to turn on vertical mode in fbneo core’s options, is there another way, within the shader, to rotate the image?

In the next version I’ll change the method. For now, in fact, you need to turn Vertical Mode ON on core options. I’ll change that to read the uniform Rotation and auto rotate according to that.

Another showcase from Android. This time I didn’t use the “FULL” aspect ratio which messed up the view in portrait orientation. Instead here I use core provided aspect ratio with integer scaling, combined with bezel that seamlessly connects to the overlay. This way it works on landscape mode:
And it works as well in portrait orientation:

TUTORIAL UBORDER - Creating Your Own Preset: The Easy Method
With the latest release, it’s a great time to explain how to use some parameters to create your own custom preset featuring the background of your choice.
This tutorial is designed to be simple. We’ll start by using a pre-existing, well-aligned border created by Duimon. It’s already centered, with bezels and with frontal and symmetrical view. Our main task will be adjusting the frame and reflections to match the border. Let’s begin!
Steps
1. Choose Your Border
From the Duimon-Mega-Bezel-Potato pack, I’ve chosen a Neo Geo AES background as an example. Copy this border into the uborder_packs/Spooky TVs/border folder:
2. Duplicate and Rename the Preset
Inside the uborder_packs/Spooky TVs folder, copy the Spooky TVs.slangp preset and rename it appropriately for your new border:
3. Open the Preset
Open your newly renamed preset. You’ll see several parameters, set to work with the original spooky.jpg border:
4. Update the Border Parameter
Edit the BORDER parameter to point to your new Neo Geo border:
5. Load and Test the Preset
Launch Retroarch, load a test screen (e.g., the 240p test pattern), and apply the preset. You’ll notice that the image and reflections are misaligned:
This is where many people struggle and give up. Let’s fix it!
6. Enable Reflection Adjustment View
Activate the Reflection Adjust View parameter. This will display the reflection bars, making them easier to align:
Here, you’ll see most of the reflection bars are hidden behind the frame.
7. Make Reflections Visible
Adjust the reflection parameters (e.g., width, height, center, and thickness) to make the bars visible. In this case, the bars end up centralized because we’re using a well-designed background from Duimon:
8. Adjust the Frame and Curvature
Next, tweak the FRAME and GEOM'S CURVATURE parameters to fit the frame within the border’s screen. The red-highlighted parameters in the image below are the ones to modify:
9. Align Reflection Bars with the Bezel
Now, adjust the reflection parameters (highlighted in red below) to position the reflection bars next to the frame:
10. Preview the Final Reflections
Disable Reflection Adjust View to see the final reflections. You can increase the reflection strength parameter to make them more prominent. The result should look like this:
11. Save and Update the Preset
Save your progress as a simple preset. Then, copy the updated parameters from the simple preset into your original preset. Be sure NOT to delete the original parameters—just update them with the new values:
12. Finalize Your Preset
Finally, round off any parameters as needed. Retroarch occasionally introduces rounding inconsistencies, so this step ensures a cleaner preset:
Conclusion
That’s it! When you load the original preset, the border and reflections should now align perfectly. This method works best with well-designed borders, such as those by Duimon. For random TV images or misaligned backgrounds, additional tweaks may be necessary.
Enjoy creating your custom presets! If you have questions, feel free to ask.

Just tried and I couldn’t make it work.
I did the update from online updater and copied over borders_pack-24-12-08 & content_shaders_pack-24-12-08

Which game? Which preset? Core?
This is a feature that needs more tests. I made it work with some arcade games on FB Neo only.

FBneo, I loaded FB-Neo_Vertical.slangp (from duimon’s potato presets)
Setting TATE -> 0
does rotate the game but not the background

Sorry, I didn’t update RA repo yet. I just updated my repo.
Go to my repo and update your uborder to v0.0.3. You’re using 0.0.2 from RA repo.
I’ll update RA repo in the next days if I don’t find any bugs.

oh, ok! I thought that update was already live! I’ll check your repo!
EDIT:
copied over new version and it seems to work properly with tate=0

You reminded me now that I had forgotten to unset that param. It should rotate automatically. I just updated the borders pack now. You don’t need to set that param, the game will rotate seamlessly. That param is just a last resort.

Nice, I will try later!
One question:
is it correct that changing Reflection_Center X/Y, it moves not just the reflection but also the games-screen as well?
1 Like
Yes. At first I thought it shouldn’t, but everything I tried to move without the frame resulted in wrong reflections, so I fixed it. The procedure you should follow now is: first move the frame (using frame centering params) into the center reflection bars, then use the reflection centering to move frame/bars to their final position. After that, use other params to zoom in/out the frame to desired size and reflection params to adjust the bars (size, thickness, warp, etc).
If I find a way to work without that constraint, I’ll update it.

I think I got it, and it’s working! 
Tate set to 0
Just mind that presets from uborders pack have tate set to 1 and switching to 0 rotate the image but not the reflection, I tried FB-Neo_Vertical.slangp (also I don’t think it cendered)

Not anymore. As I said earlier, I’ve updated the border’s pack with those vertical presets with rotate param set to 0.

Holy! I just saw I forgot one preset. Thanks. I’ll update now. CAB_Vertical is correct, though.
EDIT: Now it’s updated and fixed. Thanks for the tests!

Tate is now 0 but centering and reflection are not correct I think:
Try this settings for: Arcade_Vertical.slangp, FB-Neo_Vertical & MAME_Vertical.slangp
geom_center_y = "0.000000"
bezel_center_y = "0.000000"
reflection_scr_distance_x = "-0.023000"
reflection_scr_distance_y = "-0.032000"
frame_w = "0.812996"
frame_h = "0.338000"
bezel_w = "0.095000"
bezel_h = "0.066000"
reflection_strength = "0.070000"

Ok, I’ve noticed that. Looks like I calibrated using a non-vertical game, LOL. I just fixed it and updated border’s pack one more time. Thanks.
