I've never dabbled in dedicated emulation consoles before the AYN Thor but I'm glad I took the plunge. It captures the feel of a 3DS XL quite nicely. The dual screens and form factor capture that crucial missing element for the DS and 3DS that was missing from PCs and most other emulation hardware.
Having to set up the software can be tedious but once it's done and you finally get the chance to just play, it becomes a transformative experience. So far it's been a blast playing Nostalgia with upscaled resolution, it really shows just how much detail the developers put in but was lost due to the original limitations of DS screens. Being able to fast forward, apply cheats, and use save states vastly improved my experience from the first time I played it.
I bought the 16GB version on the hopes of emulating the PS3 and Switch and maybe PC titles one day if I get the itch to go that route. For now it's just such a pleasure using this as my daily driver.
