Thank you for all the feedback!
I was actually thinking of using Retroarch, sadly there are no useful
tutorial of it running on 3ds properly, the ones available are extremely outdated. I can run it in PC and in consoles like Wii U just fine, but don't understand or can't manage core, assets and other stuff on 3ds. Can you make a noobproof
tutorial on Retroarch in YouTube? Addressing specific issues, for example, which core and assets should I install if I only wish to play PS1 games?
Edit: On a side note, is it possible to use Duckstation in 3DS? I know its not as its built for PC and Android which is way more powerful than 3ds. But I was just wondering if a simplified version without all graphical enhancements, can be run in 3ds. Also the new PS1 Bios extracted from PSP is very useful, I hope everyone is using that.
