    emulator lag issue

    I recently softmodded my Wii, downgraded to System Menu 4.1U, and installed some emulators like FCE Ultra GX 3.3.4 and Snes9x GX 4.3.2. The emulators have a lag issue; I press a button on the controller and it takes roughly a quarter- to half-second for the input to be recognized, making most games unplayable.


    I have seen others with this issue but nothing I've seen recommended fixes my issue. I tried moving the ROMs from external HDD to SD card, I've tried both the classic controller and the regular wii controller, etc. Some have said the type of video connection used makes a difference (I am using composite cables) or changing the video output mode might help (my Wii is outputting 480i to my HD plasma screen; incidently the 480p otion is greyed out so I can't even try that) but regular Wii games play just fine without any lag - shouldn't ALL games have lag if this were the issue?


    I'd greatly appreciate any other ideas to help me fix this issue.

    This happens because the games the emulator emulates polls for input during VI's ( Vertical Interrupts ), In both of those emulators they poll for input after the VI is triggered, there is approximately a 1 frame difference between the input and the next VI, so the inputs are updated after the game reads the controllers status, which makes the updated values to register on the next frame. I really don't think there is much you can do to fix this. It isn't a video output issue at all, just how the games and the emulator grab input. You get used to it though, just play Killer Instinct for a while and you'll see it really isn't that bad.

    The lag I am experiencing is much greater than 1 frame, its closer to 15 frames or half a second. I could live with 1 frame of lag. Thanks for the input. Any other thoughts?

    Hmm, 15 frames ... do you use Composite or Component, and do you have an older ' box ' TV to try it on ?

    That's your issue. Your TV is deinterlacing and denoising the image, and this can cause 100ms of lag or more, regardless of the source. The reason you notice it while gaming is because your inputs are directly influencing the onscreen image.

    That's because you're using composite cables, and 480p requires component. Get a decent set of component cables (third party should be fine, I've used aftermarket cables on other systems with no issue, although the Wii component cable I'm currently using with my CRT SDTV is made by Ninty) and switch to 480p and you will minimize, if not eliminate, lag (depending on the TV). Also, your picture won't look like a dog turd with component cabling.

    Alternately, if your TV has some sort of "game mode", try turning it on. If it does, that should eliminate much or all of the processing that the TV would normally do to a video image and minimize lag as well (although the picture may then look more noisy, as all that processing and noise reduction takes time).

    Some games are more sensitive to lag than other. I guarantee you all your games are lagging, even if you don't notice it. Try playing something like Guitar Hero or Rock Band on your setup - even being a Wii game, it will have to be calibrated for your lag before it's playable. For some reason older games tend to be more sensitive to lag than newer ones, perhaps due to a difference in how they poll for controller input. Whatever the case, it's very annoying. The only way to have 100% lag-free gaming with a Wii is to use an old-style CRT. With an HDTV, even on the best possible setup (component cables, 480p, game mode) there is still likely to be one or two frames of lag, since HDTVs don't generally display the image as it comes in, but they buffer the whole frame then dump it to the screen. CRTs display the image as it comes in on the wire. Admittedly, it's my understanding that plasma TVs aren't as bad as LCDs with lag, but as I don't own a plasma (and don't run my Wii on my LCD HDTV), I wouldn't know.

    I see component Wii cables on Amazon for under $2 so I guess it won't hurt to give that a try. Thanks all for the input.

    Also, Folks on Reddit are telling me it was a bad idea to downgrade my System Menu from 4.3U to 4.1U. I went by Guides Bot guide here on Wiihacks; in the first post, Chapter 2, Part 2, near the bottom there is an expandable box called "Downgrade to/Upgrade to/Install System Menu v4.1 (Optional, but Recommended!!)": http://www.wiihacks.com/recommended-...d-any-wii.html. Can anyone comment if downgrading is a good idea or not?

    Looks like my previous response has been locked for modderation... Anyway, I found some 3rd party Wii component cables on Amazon for $2, I'll give those a try and look to see if my TV has a game mode, thanks for the advice.

    I do have an old CRT TV in the basement, I'll give that a try.

    Thanks to all for the responses!

    My component cables arrived today. After making the switch, everything works perfect! I didn't even switch to 480p output in the Wii System Menu, all I did was swap the cables, and the difference is HUGE! There is no perceptible lag issue and every game functions exactly as I would expect. Now I can play all my old NES favorites... there goes the next several weeks of my life!

    Thanks all for the help and advice!

    When playing Wii games, I'd still suggest you switch the output to 480p, you may or may not notice a difference, some people can, other's can't. But for those who do notice, they won't go back to 480i.
