Doesn't appear to work with NES Classic

Didn't work with my NES Classic Edition. Haven't been able to make sure that it wasn't defective on a real Wii yet. Not leaving a rating until that point.

The 1 star reviews seem to have been made by people who don't realize that this can't fix EVERY nintendo, just a lot of them. If the problem with your NES stems from a bad connector, then this product is going to work just dandy. If the problem lies elsewhere, then this isn't going to do any good. Sadly, as far as I know, there's no way to tell the difference between a system that does need a new connector and one that does not; other than buying a new connector and trying it out. The other thing you need to watch out for, something that I had issues with; is that you need to test as many games as possible before you give upon the connector. Since most of my games have come from yard-sales and thrift stores, I had no way of knowing if they worked before fixing the system.

Bottom line, if you've got an NES that doesn't work try this, it might fix your problems. Also, be sure to test 10-20 games before you deem the procedure a failure; something may have damaged some of your games in the past 25 years, and you just didn't realize it.

DIdn't work for me either. Tried it on a regular old SNES. It does nothing. No picture, no sound, as if it's not even plugged in at all (but it is.) Other reviewers are saying the same. Maybe at this price these are just going to be a hit or miss. Mine was a miss. Oh well, it's returnable and at this price it was worth a shot!

This system works great!  My original NES died and this one works perfectly.  NO resetting or difficulty in rebooting like the original 'hinged door' 8-bit NES.  Key is:  it works with the original NES controllers!  The controllers that come with it suck.  I threw them out.  But am happy as can be because I have a system that works and will last for $20.  Also, FYI, connection is the standard Red/White/Yellow A/V RCA jacks (standard tv, dvd, vcr analog connection).  I recommend a 2:1 splitter/adaptor so you get stereo.  I think there is only one audio jack (like the orignal NES) but I split it into two (red/white) so you have dual speakers (Left and Right) not just one.

One downside is that it is hard to remove a game.  There is no eject button so I couldn't determine how to eject a game.  I only have one game, the best game ever - Tecmo SuperBowl, so I don't really care, but I found this explanation on another review (thank you):

The system is designed to grip your games tightly to maintain even connections with the cartridge. Although it does this well, it may cause the cartridge to be difficult to remove when finished playing. All you can do is, as carefully as possible, remove the game upwards with even force. Unfortunately, the RES doesn't hold your games in horizontally (from front to back) tightly. The game can wiggle back and forth freely and if moved, the game will freeze. (just wedge some cards or something for spacers on each side to fix this)  Be sure not to touch the game once its up and working.

Worked perfectly with my original NES and SNES controllers!

There was no difference between the original resolution and the "upscaled" one for my N64. I'm playing on a 48" HDTV. It could just be my TV but I've given up hope already. Looks like I'm out to find a CRT.

I love the classic gaming consoles! Having grown up with NES, SNES, etc, I have started collecting a few.. have an original Genesis 1 16-bit, NES and SNES. The problem, of course, is that they all use the same RF/coaxial connection... Solution: THIS!

I had managed to get my NES and Genesis connected by AV, and thanks to this product (and&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/uxcell-Black-3-Ways-Splitter-RCA-Audio-Video-AV-Switch-Box-Game-Switcher/dp/B00GN5BZYQ/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">uxcell Black 3 Ways Splitter RCA Audio Video AV Switch Box Game Switcher</a>) I now have all three connected by AV :D

Does not work. I bought this for my retro gaming systems. Hooked up the snes and all you get is a blue screen and a message that says "no signal 720p or 1080p." Will be returning for a full refund.

I bought this specifically to try to improve the performance of our ps2, but similar to what someone mentioned regarding the Wii, there doesn't seem to be a way to get the disc to play in the ps2.  If this product will only work in a select few game consoles, perhaps that should be specified in the description.

Ordered 2 of these, On one of them the Left Shoulder button did not work. On the other one the Up on the Dpad doesn't work. And neither on of them can you have multiple buttons pressed at the same time for combos. Such as Start+Select for exiting games in Retropie.

I bought this to hookup a Nintendo classic (the mini one) in our SUV that only has rca inputs. I can't make it work. I can hear the music for about one second then it stops. Never any picture. I tried it on a TV as well and can't make it work with the Nintendo either. I did plug an Xbox One through it and it worked, so I know the cables are good. Was hoping my kids could use it this weekend for a 13 hour road trip. Disappointing.

I'm not gonna lie, this thing seems pretty cheaply made, but what can I say? It works. I've only used it couple of times at this point so I can't speak to the longevity of its use. I bought this to use with my raspberry pi and the retropie OS. It worked as soon as I plugged it in, and my brother and I were able to play the old NES games we love with my old PS1 controllers. Pretty awesome!

I may need to spend some time to have this configured properly.
I got it a month ago when my brother was in town and the goal was to have some good time with old games.
Playing them on a computer is better as the graphics are boosted up to 1080) so in a 42" tv they look awesome (you can see the polygons but not the pixels, as they are now rendered for high definition, instead of 360 or 480 as Nintendo 64 did).

It always take a while to setup a laptop to play something in the screen, but this time calibrating the N64 controllers was unpleasant and took away the first minutes magic of what we were about to do.

That night I ended up giving up and we used XBOX controllers. They are good but not excellent for games like perfect dark or goldeneye. Plus I have a special controller I bought for N64 in his golden years, a Nikko pad, which is very well made (it has lasted up to now). So far I have only spent about 1 hour trying to have this thing work, by doing what the internet says about calibrating it and setting up the Project properly. Didn't work (not even with the original controllers).

As soon as I find a proper way to have them work I'll update or I'll update that you can't play.

Update: (I remember having done this before but for some reason the update is lost).
The problem was with my controller, not with this thing.
It works now, although I haven't managed to calibrate it exactly with the same precision as for Goldeneye (that or I'm losing aiming). Doesn't matter, you can play fairly good any game out there :)

This worked perfectly in making an old 8 bit Nintendo work on an HDMI Tv - alas, I can play my old school games on the original machine!

Just got this for use with new 2nd (Nintendo) controller for brand new Wii, using the basic Wii Sports that comes with the Wii, e.g., Boxing.

It doesn't work.

First, instructions are incorrect -- probably a bad translation.  They say to insert ONE battery, but it's obvious that with one battery in, it won't get any power, and sure enough, nothing happens.  Presumably they meant "reinsert one battery".

OK, insert the 2nd battery and press the sync button, and red lights blink on both parts (the hand held part and the adaptor part you plug into the Wii remote).  The instructions say that the red blinking light means "connected", but that light blinks on the adaptor even if no batteries are inserted.

The Wii never gets past the screen saying "Connect the Nunchuck".

The same thing happens with either of two Wii controllers.

Maybe this particular one is bad.

using it with a rasberry pi setup with retropi for NES, SNES, etc. Works well. Build quality is very similar to the original SNES controller it emulates in form. USB cord is unfortunately a bit shorter than ideal.

Does not work with some games, like F-Zero GX, because it senses that it is not an official Nintendo memory card.
