Retroarch overlays in 2.0 ?

[Okfig]

Hi everyone,

As the title says, I want to use overlays in retroarch.
When put in .retroarch > overlays, the folder is empty.

Am I doing something wrong ? Maybe overlays are not supported right now ?

Thank you for your help !

Short: No support for overlays in Miyoo's RetroArch

Long: Overlays are unlikely to happen cuz they need GPU by RetroArch to be drawn over surface, like shaders. It would help if F1C100S would have some API to perform 2D graphic operations (like MMini does I believe with its GFX engine to do overlays), otherwise there is possiblity of drawing up to 4 layers with DEBE (two already in use by DOUBLEBUF my guess) which may come with noticable overhead if using more than 2.
Possibly it would be easier to just rewrite overlay code to do simple SDL blit PNG image on top for MIYOO platform, without mixing of actual video output on screen.

Thanks a lot for your answer !
In your opinion, can people (like me) who doesn't have any coding knowledge can rewrite overlays codes ?
Do the Miyoo CFW team consider the possibility to do it ? I don't measure the amount of work necessary.

Best regards !

If you start learing it would be the best to try your strenght in porting (cross-compiling) some app by adding also a small change in code (new logos, fixing some bug).
The RetroArch code is kinda large and not so easy to understand IMO by first committers (including us😅)
