I found after time the cart slot get finicky, I mean even the slightest movement of cart and game will glitch, also the flimsy cart slot cover broke hinge on one side, I just removed the whole damn thing. Emulation is typical of most famiclones, YES you can use the converter on it for famicom games, I have done it. Lastly I had to re-solder one speaker wire when I noticed sound was coming out only one side. It is worth what you paid for sure, I overpaid lol.

This things looks RAD!
