So yesterday, I bought Ocarina of Time on Virtual Console. I figured it was about time to replay the game, and I figured I would do it on my Wii U rather than on my N64, seeing as how it was more convenient for me. Well, that was a sorry investment. Turns out I could've saved myself some money to buy an amiibo. Two glaring problems emerged from playing this version. Keep in mind that I can't say the same for Wii VC, and other people have reports of the first problem on other N64 VC games:

1. Input Lag - This is a serious problem. The input lag is horrendously noticable. It takes about a half second for your inputs to be recognized. This is obvious in parts of the game where you have to do something quickly or take a hit, such as shielding, which I first noticed Inside the Great Deku Tree while fighting Deku Scrubs. It's unacceptable and it makes things like beating enemies more difficult than it has to. Now take that lag and apply it to a 3D platformer like Mario 64, which in many cases requires precision. Verdict: Don't buy some if not all N64 games on Wii U VC if they take even the slightest bit of precision, because you WILL be thrown off.

2. Analog Stick Sensitivity - This makes the Shooting Gallery near impossible. The sensitivity was emulated very wrong. It may be more of a problem with the original N64 not quite exactly having full analog movement, but this could've been optimized for a normal modern controller. I'm not quite sure how to describe it. It's much too sensitive while still having that classic N64 stiffness of the camera. I first noticed this problem also in the Deku Tree, where manually aiming at some Skullwalltulas was a hassle and left me frustrated.

3. Can't Map anything to the D-Pad - For one, you can't expect someone to use an analog stick for something that was designed to be used with the C-Buttons. Now granted, you can map C-Buttons to other buttons, so you can use items better. But using the Ocarina was designed to be used with buttons. There is no easy way of mapping them onto buttons in a way that makes them easy to use or natural, so you are stuck with the analog stick. Using the Ocarina is much too frustrating and slow now. I'm aware this was a problem in the Wii VC version too.

That's what I have to say. Did any of you have problems with an OoT port?

Have not purchased OoT via VC but you should contact Nintendo concerning the issues. Also, did reviews on VC not alert you to the issues?

I don't think there are that many reviews of Wii U VC versions of games. It was just today that I saw a like 2 forum threads from around the web discussing some of these issues.

Well, you could have looked into the Miiverse.

Curiously I did not have problems with laggy controls, and the analog stick sensitivity is something one can get used after a while (I did), but I agree about the C-buttons for the ocarina melodies

Well, it's not the original 1.0 version of the game, so personally I wouldn't buy it anyways, but sucks that it has all those problems you mentioned.

I wasn't actively looking for reasons not to buy the game when I did. Although I am surprised not many have complained about some of these things.

Man, eShop refunds needs to be a thing.

You can refund your purchase easily

I own either version 1.0 or 1.1 on N64, considering it has no censorship it can't be 1.2. The version emulated on VC is the GameCube version, they change some interface icons to make it look like the original, though you probably already know that. I think it being the GCN version causes some of these problems.

Out of curiosity, why wouldn't you buy it if it wasn't 1.0?

Like I said, it's more of a personal thing. My first playthrough of this game was with the 1.0 version, and seeing as I already have the 3DS remake, having another censored version of the game is kinda pointless. 

I haven't played OoT on Wii U, but I have the exact same problems you listed with Donkey Kong 64. I still like it enough to keep playing it, but man, the controls can get frustrating. Some of mini-games that require precise movements make me want to throw my controller at the wall. Also getting pretty sick of using my instrument instead of getting long-range weapon out. x.x

Basically, it seems like the controller is the big issue. Not sure about the joystick controls themselves, but lack of C-buttons on the Gamepad/Pro controller means you'd probably have to use the right joystick. Maybe using a Gamecube controller adapter or being creative with how you map buttons might solve it...but it's still definitely a problem.
