I wrote my first product review! This one is on the Anbernic RG503 handheld emulation device.
Although I didn't mention it in my review, I can confirm that PS1 emulation does work. I've also added movies and TV shows to my SD card and the thing plays them quite well, including movies in 1080p.
It's really quite surprising that a Chinese emulation handheld is actually superior to the major consoles that Nintendo, Sony, and Microsoft offer. I mean these handhelds could hook up to TVs long before Nintendo had the idea.
Okay. Playing Nintendo DS games on this thing somehow freezes the system to the point that you have to reflash your OS. Though, you probably wouldn't want to play DS games on this device anyway because there is no touchscreen or anything that can practically be used in place of one.
Though Mario Kart DS worked fine. Super Mario 64 DS was the one that hanged. The game requires you to touch the touch screen to start, so I had to quit, but exiting froze the thing. Hard resetting corrupted the OS.
This may not be a problem on other operating systems like JelOS.
