    Hey everyone,

    a few years back I bought the OSSC (the one with HDMI) and I love it so much, I guess it’s one of the best gadgets I’ve ever bought. After some time, I started to clean all my old consoles, mod them, softmod them, buy cables… and reconnect everything via the Hydra Switch, or directly to the OSSC itself (VGA, component etc.)

    Thanks to the homebrew community and the 240p TestSuite, I managed to get EVERY console to look stunning. This was not only because of the wiki, but also this forum and many others, so thanks to everyone here. 😉

    Did I say every console?
    Well… except for one. My Pal Wii has some weird problem. I softmodded it years ago and I left it as a pal system instead of changing regions internally (from what I’ve read the NTSC software doesn’t output RGB?) and connected it to my OSSC with the official component cable. It was brand new and still in the box, so no damage or anything.

    The thing is – the 240p TestSuite looks perfect everywhere, except for the Wii. It is driving me nuts. The pixels are as sharp as I can make them (even more than many people say online) but there is some weird haloing around everything. It feels like in the old days when the TV was slightly off and you had to calibrate the picture to match the different layers so it losses that haloing.

    From really far away you can’t tell much, but since I use it on my 4K TV and it’s not that far away, I can tell.

    Has anyone any idea where the problem could be and how I could fix it?

    For more details:

    – The Wii is the very first generation, but I use the “480p pixel fix” which was introduced later last year.
    – The Wii is in 4:3 aspect ratio, not 16:9 so the pixels are not anamorphic stretched
    – 480p is enabled system wide
    – All games have the same problem, including the menu
    – every other console looks perfectly crystal clear, even the xbox with the component cable to the same port, so the OSSCs port can’t be the problem either
    – I used all settings from the wiki and had a deep look into FireBrandX’ recommendations
    – the OSSC has the 0.85 software
    – I know it’s a small details but guys really, it drives me insane LOL

    I also captured a few off-screen pics to show what I mean. The problem isn’t the pixelshift (which I tried to perfect but it never lines up correctly) but the “haloes around the pixels”

    It would be awesome if some could help me out. I can also give a ton of more detail if asked

    I assume you are using component cables to connect your Wii to the OSSC? The Wii’s component output is notoriously inferior to the GameCube. Most wouldn’t notice unless they were displayed side by side. Then again, not all cables are built equally. Are you using the official Nintendo cables or a third party set? Some third party cables are well built, others not so much. If using component cables, I generally go for official cables whenever possible for the best results. Then again, I’ve used a Wii2HDMI for years and never had any issues with ringing artifacts.

    Yeah, as I said I connected the Wii directly to the OSSC with the official Nintendo Component Cable, fresh out of the box so there is no tearing or any damage whatsoever.

    I used the Wii2HDMI before I had an OSSC, but I could never go back to that again lol

    Missed that detail in your post, sorry. This is what I get for writing at midnight.

    Have you tried using different cables to see if the problem persists? Or perhaps just use the OSSC’s default settings? I’m aware that profiles for the OSSC exist, though honestly I’ve never used them myself. I usually just fire up a console and select which line multiplication I want. So simpler.

    I don’t have any other cable to test out anymore :/

    the thing is – I really want the best out of the OSSC. It works, but I want to get the pixels cleared up

    Have a read through https://www.retrorgb.com/wii.html

    The wii has poor video quality to begin with. You need to bypass it (e.g. with a wiidual) to get perfect output.

    I have. I think I’ve read the whole internet on it Wii picture quality, but there are a few things either not mentioned or not really seen.

    I know the Wii has a “weird” picture quality, and I know the GameCube has a better one (actually years ago I said that in GBATemp and in the shmups forum), but for now I’m concentrating only on the Wii games.

    And yeah the WiiDual exist(ed) but my Wii is a RVL-CPU-01 which isn’t compatibly with the WiiDual (only for CPU-40 and above) and I bought the OSSC because of not modding too much. I can get away with soldering stuff like the PSIO for the PS1, but I’m really NOT good at soldering flex cables. I hate them :/

    Besides that, some say later revisions of the Wii have better picture quality, many say the opposite. MyLifeInGaming (YouTube) said, they see no difference. Others say there is a difference, but only in 480p content (meaning 480i looks everywhere the same, but the compiler of the progressive picture is superior in later models)

    Has anyone a Wii on the OSSC with as much work done to the picture to show a comparison to my shots? Because I don’t see why there is that haloing I was talking earlier about. I am starting to wonder if the unit has some capacitor problem or if it’s somewhere else :/

    Back before I modded my wii I had done similar amounts of work, but sadly I didn’t take any screenshots. Hopefully someone else with an unmodded wii can chime in.

    I hope so too. :/

    One thing for the mod side of things – the DCHDMI mod looks 99,9% the same as the Dreamcast unmodified with a Toro Box and some work on the OSSC. It’s so much identical that I really hope I can archive the same with the Wii in some way.

    It feels like the Wii picture is out of sync for some reason

    Did you try adjusting the phase? The screenshots do look like it’s a bit out of phase.

    #39763

    Yes, I tried every phase setting there is, and 180 seems to be the closest one to a clear checkerboard. I also used all the settings from the wiki for the Wii

    Given that the ringing is symmetrical about the edges, could this simply be a product of oversampling and output filtering in the video encoder of the Wii?

    #39765

    But with 480p, why should it oversample? I would so much take a look at a second Wii user so I could compare the pictures :/

    #39766

    I imagine that it oversamples to control the output bandwidth. They probably didn’t aim for a very high output bandwidth in the first place.

    Are you trying to play Wii games or GameCube games? If you’re primary need for a Wii is to play GameCube games and the Wii’s output is unsatisfactory, maybe a GameCube might be a better option.
