I've tested a handful of games but only played a lot of Final Fantasy 1 on the GBA. It runs well. Though there are slight audio issues, but not enough to really complain.

Everything retro has run fine so far. Ape Escape, Metal Gear Solid, and Tomb Raider on PS1 seemed to play just fine. I didn't put a lot of time into them but enough to assume it would play the whole game with minimal issues.

The only issues I've had so far is a stuck green pixel. I only notice it when the console is booting so, again, I can't knock it too bard.

This is a solid game console. It’s exactly what I was looking for as I wanted something for Sega and older. The one thing I will say are the buttons are raised higher than I desire making tough to slide across buttons for certain games like Mario (trying to sprint to jump). Thinking of buying the newest model to play some later consoles like PS1 and Dreamcast

I was really impressed by the device. I had read good review on retrododo.com and was expecting something good, but this device combined with the custom ArkOS operating system, is really great! An excellent device for a great price tag! I do get regular device freeze, but it's not clear if it's arkos related or device related. It seems to happen more often when the wifi dongle is on the device.

Excellent build, excellent emulation experience.

This console is really awesome. It's quite well made, particularly considering it wasn't made by a mega corporation company, along the likes of Nintendo. It feels good to hold, the inputs are responsive and have a satisfying click to them.

I'm a programmer and tinkerer, so I really love how you can just swap out the operating system on it, SSH into the device, or even load your own software on it. It really adds a whole extra dimension to the system and lets you try your own games on a handheld easily. Particularly if they are SDL2 based since many of the OS options for this device come with it.

As running games it does a great job at it too. The screen dimensions are particularly suited for the GBA though, being twice the screen resolution. However because of that, any other "regular" system like the SNES or Genesis won't display pixel perfect because of the screen dimensions. It's not a big deal though, I just set it to scale games to fit 4/3 with bilinear filter on. It sort of gives it a more "authentic" feel, somewhat emulating a CRT screen blur. And it's less battery demanding than using a CRT filter too. Though if you plan to play more standard 4/3 resolution games and want it pixel perfect, it might be wise to compare the other models offered here that have the screen for that. It's also really nice to be able to enter sleep mode with it waking quickly so you can go in and out of games throughout the day(s). Ever since I got used to that from the modern Game & Watches and Switch, it's been really hard imagining not having that quick jump in and out functionality in a handheld and glad this system does a great job at it. Or at least the OS I have does, which is 351elec.

The battery life seems decent too. I've been able to have it going on two days without a charge while doing some frequent pickup and play throughout the two days. Great to have on the side ready to go.

I also appreciated the WiFi dongle that was provided. While sure it'd be nice if WiFi was built in, this was still really wonderful not needing to go out and find an adapter that would work with the system and I could connect wirelessly right out of the box. Definitely the next. best thing. In a way it's also nice having it as extra hardware because it easily reminds you about it. That way you won't forget and leave WiFi on when it's not needed to help conserve battery power for longer play.

Overall, a great system for retro gaming and a really cool system for tinkerers to mess around with.
