Ok, my RS-69 is here as well - the screen wasn't fixed properly, so I had to disassemble the unit and add a bit of sticky foam to remedy that (very easy to do so, 6 external screws and 3 internal).
-Unit is larger than the PokeGear, 7.8mm*11.5mm.
-The shell isn't as nasty, but not liking the bumpy finish too much.
-The screen isn't great, bad viewing angle especially when looking from left.
-Was extremely lucky to somehow change the language to EN by accident. After managing to do that, everything seems to be in EN, thankfully.
-No way of remapping the controls as far as I can tell. So unless they are already mapped in a way that makes the game playable, you are out of luck.
-One savestate per ROM, it seems, and no support for internal saves. This means you are one bad select away from destroying your progress.
-Comes loaded with some 3k+ ROMs (for all supported systems) of various quality and languages on a 8GB microSD card. The operating system is on the unit's internal memory. With no SD card, you are allowed to boot and change the settings.
-Seems way slower than the PokeGear, Doom2 runs at 0.5FPS (was perfectly fine on the PokeGear).
-There definitely is some screen tearing, and some ROMs don't work (WarioLand4, Wolf3D, Sonic1 and 2, despite coming loaded on the SD card).
Conclusion - nope. Get the $10 hdmi clone of the AtGames clone, it has a smaller screen, but it does more and is better at everything.
