Can overlays and shaders be added to games on the PSP port of Retroarch?
Shaders definitely not, but overlays are possible.
How do I add overlays on the PSP port?
Sorry, by “possible” I didn’t mean “they definitely currently work,” just that they are technically possible. I’m not sure if they’re hooked up in that port.
You can try loading one up by going to settings > onscreen display > onscreen overlay, but if it fails to load, there’s not much to be done about it at the moment.
are things better on psvita?
I’m not sure. I don’t own a PSP or a Vita, so I don’t know much about either port.
I just thought of something…what about the Nvidia Shield portable?
Overlays work fine on the Shield portable, as it runs Android.
And what about shaders?
They work just fine with it, as well. It has a full Android stack with support for GLSL shaders, etc.
Well Shield portable it is. It’s a full go for this project. Problem solved
