Is that a NES or a SNES?
Also, dat Xbox <3
that is a SNES and a NES. its a Retro Duo. i play most of my games on it so as not to damage or wear out my old NES and SNES. theres a few games it cant play, and a few games it doesnt play super well, but the a mjority of the library(gotta be at least 95%) it plays fine. and unlike other NES-on-a-chip and SNES clones, it can actually play games like Castlevania III and Super Mario Legend of the Seven Stars(really awesome RPG). with the NES you can still get that bleh NOAC sound though, but at least you can fix it if you solder a resistor to the board.
also there are no tabs in the cartridge slots, so it can play super famicom games just fine. regular famicom games still require an adapter however.
Cartridges fit snug but not tight. there's no eject button, so you gotta pull the carts out manually. its no problem though - just be gentle and you'll be fine.
However, if you do ever break a Retro Duo, they are very cheap to replace, and there is a ton of em out there (i bought mine for $60, i think they are even cheaper now)
another nice thing is if you have for example, the SNES powerpack, it works on a retroduo. im not certain if the NES powerpack works with the latest retroduo however (that is v3.0) but the retroduo is also the only NES clone that can properly play Castlevania III.
the controllers arent the greatest quality, but they are cheap, easy to find and replace, and at least while you are using them they work very well. also the retroduo does accept genuine SNES controllers as well (which i highly recommend - those things are tanks, and they're just overall a wonderful controller)
and lol i love all of my systems equally Norik...though goddamn i hate standard XBOX and XBOX360 controllers >.< at least the batman controller i got sitting there makes for a good replacement. But lets just say a more traditional stick layout and cross-style dpad design are more suitable for my gaming needs.
also wired controllers FTW!!!! ^-^
