/vr/ - Retro Games

Good evening lads
Hope you’re having a wonderful day.

I’ve got this conundrum where I have a ps4 pro, Mac with openemu, vita, DSi, n3ds, n2dsxl, genesis mini, snes mini, wii
(Used to have a steam deck which I got rid of)

but i cannot stand playing games that were not “meant” for their original hardware, pr lor related hardware
I can only play psp games on vita, nes games on my snes mini, etc
One issue that I have, is that my tism blocks me from fully enjoying my GBA games on my DS systems because of the black screen below - and I haven’t seen anything related to a fix for that

What’s a reliable system I can get for GBA games only?
I’ve been looking at the new Anbernic 35XX Plus, especially because of the advertised 8 hour battery life, but the 4:3 screen is of concern to me. 3:2 screen would be preferable to avoid black borders.
Any way to mitigate that? Maybe it’s not that noticeable when actually playing?

While I’m here, how do I mitigate this kind of tism when it comes to the n64? I’d love to avoid paying for 2 Wii classic controllers or 2 GameCube controllers.
I feel like I just have to bite the bullet and install retro arch on my ps4

I’d also get a ps classic for ps games if it wasn’t for the controllers that it comes with.

Cheers lads
