I love these bezeles but im wondering if theres a way to remove the curvature effect and the highlight on the screen? Also for GBA, is there any way to change the original color?

@HyperspaceMadness has provided parameters to adjust both the curvature (You also have a choice to use 2D or 3D curvature.) and the opacity of the screen highlight. (0% to make it disappear completely.)
In addition, you could replace the tube reflection image with something more to your taste. (A scratched or otherwise damaged surface is popular.)
Which color are you referring to, the screen palette, or the body of the handheld?

@Duimon, Oh cool thanks! I’m talking about the screen palette. I’m used to the colors of the emulators not the actual color of the GBA Hardware. Was just wondering if there is any option to change it

Hi, there is actually a couple color corrections in the chain for the lcd grid preset that you can use to adjust the colors. There is the GBA color parameters (which happens after the lcd grid pass) and grade which happens before (grade is a really in depth color correct)

Hi @JuRaSSiCBoY, welcome to the forum! 
This is very nice of you to say! Myself and the other contributors making awesome graphics have put a lot of effort into making this as enjoyable as it can be to use, so It’s always great to get feedback that people are enjoying it! 
Let us know if you have questions, feedback, or you feel like sharing snapshots of your creations these are all welcome.

Thank you you’re very kind! by now I’m putting and testing the HSM to all my Retroarch ROM collection. The reflection effect gives me back the feeling of playing the original console, It’s very impressive. 
By now works as it should with every platform except some strange behaviour with Beetle PSX HW emulator. When the PS logo appears the reflection frame shrinks and it is more noticiable with the “PS advice” that appears after the PS logo. The frame does not return to its position until the game starts. The same goes for kinematics.
I don’t know if this is produced by any option that I may have activated.
Sorry if this has already been reported. I’ll keep checking the BeetlePSX options to try to fix it!

This is probably because you are using integer scale in the shader, and the core changes resolution on those different screens, so you get a different integer scale as it switches between modes.
If you don’t want this I would use non-integer scale option in the shader, and set your non-integer scale to be the size you want, perhaps a size which matches integer scale at the PS resolution mode which is the most important to you.
You can see resolution information, including the resulting integer scale printed on the screen if you turn on the debug parameter which is the very first parameter.
Here’s an example

Thanks for your awesome explanation 
Seems like removing and regenerating my BeetlePSX HW config file has reduced the shrink and stretch movement (although it still occurs the frame is not lost behind the bezel).
I’ll take a look at the non-integer scale shader option, It is clear that it’s a configuration problem on my side.

Also double check your retroarch video settings to make sure integer scale is off.

Rechecked and It’s off… here’a a user who reports the same problem:
So It’s something related to the PSX emulator or console. I’m using EUR games.

In addition, make sure to turn it off in the shader as well. I think it is on by default. (That’s why it needs to be off in the RA video settings.)
This is a issue that was solved a few months back, so be assured, once you get the settings right, it will go away.

Yeah the Playstation commonly switches these resolutions during startup, title screen and game.
A good example is Strider 2 it has these resolutions
- 640x480 - Sony Intro Screen
- 512x480 - Title Screen, Cinematics
- 320x240 - In Game
To get the screen not to change size when the resolution changes all you should have to do is set retroarch video settings
Video->Settings->Scaling->IntegerScale
to off, and set the scaling mode in the shader
[SCALING] Int Scale Mode - OFF, ShortAxis, BothAxes
to 0
This should be what it is by default… Can you check this parameter and see what is there?

I realized this happens on PSX EUR region games. But it also happens with Sharp X68000 and Atari 2600 cores.
In my case, even with this care, there are still glitches, where the background image disappears and comes back immediately.

Ah this is really strange, could you point me to the Atari 2600 core and game where this happens? Is it Stella?
Also if you could point me to a EUR region PSX game which does this that would be great

Stella core for Atari 2600 games. I just don’t really remember which games the problem occurs. On PSX games, is mednafen_psx core, where did recent tests with Rapid Reload and Castlevania Chronicles. On px68k, I also tested with Castlevania Chronicles.

I’ve checked it and:
Video->Settings->Scaling->IntegerScale OFF (I deactivated it when I installed HSM)
[SCALING] Int Scale Mode - OFF, ShortAxis, BothAxes OFF (as you say is off by default)
I don’t know why BeetlePSX HW is changing the resolution at startup and title screen with these two options disabled. I’ll keep trying!
Thanks again

Ok, thanks for all the details, this helps me figure out the issue. 
I think the problem is the automatic aspect ratio which is changing as the core resolution changes. To fix this set the [ ASPECT ] Type parameter to explicit, and then it will use the explicit value which is already set at 1.33 by default.
To help me make a more permanent fix for the auto aspect ratio could you turn the debug screen on (1st parameter) and take a snapshot when the screen gets smaller? That will give me the core resolution that I might be able to add to the auto aspect ratio so it guesses correctly in these situations.
