Depends on how you want your games, legal or illegal. You buy that and your NES games are legal but then there are roms and many many of them.
Don't buy it this console has several issue. Like the cables are too short (compared to orig. console), the HDMI is lagging (not fixable). And you can't get more roms on it (officially) there are only hacks to get/manipulate the rom. They meant well with the remake but it's not worth. Emulate or play on orig. console.
It was sold out before I even considered buying it I probably don't need yet another emulation device, anyway...
Do you mean the nintendo switch ? My friend wants it he's waiting until this summer bcuz of plausible bugs
