ANBERNIC RG 557

Justo como lo mencionaron

Incredibly comfortable device, the battery life isn't the best but besides that I have almost no legitimate complaints. Kills PS2/GC with very little tweaking and basically comes as ready out of the box as you can get with an android handheld. Sticks are small but they are so great you'll forget about it.

I'm amazed at how well the RG557 works out of the box. I'm not very tech saavy as far as emulators and optimizing them, so I rely on something that works well right out of the box and this one delivers. It does have a way to automatically notify you of firmware updates which is highly recommended. The UI is pretty easy to learn and use. Coming from an older RG353P, some ROMs that wouldn't run at all seem to run fine on the RG557. It's crazy to be able to play PS2 and N64 games on a handheld (though there can be lag at times on games like SSX)

The unit itself is very comfortable to hold and I've been able to game on it for hours without cramping up my hands. The screen is amazingly clear and bright. It's also a touchscreen as well which works flawlessly. The sound quality on the bottom firing speakers could be improved but I'm not an audiophile so they're fine for me.

Overall the unit performs very well. ROM load time is almost instant for all and as mentioned PS2 racing games may experience some lag and I'm not sure if that's expected and/or fixable but I'll have to do some research to see how I can optimize settings to improve on that

Amazing performance, but it was impossible to find content or to migrate old saved games from a Linux console

Incredible handheld portable game.
I love It. Excelent performance in retro games.
I'm looking foward to see what more this machine could do.
