Question 480i for Gamecube

[Nico128]

Hi

I have a Gamecube PAL 480i with a Samsung UE40D6510 102cm (year ~2010)

I used to connect my GC directly to the TV but my Samsung SCART adapter becomes tired. That’s why I connected the console to the OSSC.

When using passtrough mode, I find the quality good enough for playing.
x2 mode works but there is the flickering image because of the deinterlacing. It’s specially annoying when reading texts… I didn’t noticed any better image, so why should I x2 ? I’ve read that some people uses x2…what’s the benefit ? Would the quality be noticeableo only on larger TVs ?
(x3, x4 and x5 don’t work)
Or does it depend on the TV’s model ?

1) First, passtrough with/without scanlines. Then x2 with/without scanlines. Finally, passtrough again.

Do you have any advice to get a better image on Gamecube with OSSC (parameter to change, …) ?
I tested to run a game in 240p with Swiss. x2, x4 and x5 are working. I still prefer the 480i passtrough.

So no problem I can play in passtrough, I just wanted to be sure there is no other way for me to have a better quality.

Note: I own an official GC component cable, does it works if I connect the audio via composite cable to the OSSC ? Will the OSSC mix up the signals ?

Thank you

Bob deinterlacing is used because it’s fast but it doesn’t look particularly great in my experience. Even compared to a CRT. Considering you have a PAL GameCube, I’d recommend just getting a Wii with component cables to play games in 480p and keeping the pal gamecube for use with the gameboy player in RGB. Component cables for GameCube are expensive regardless of whether you get the official ones or not. And pal gamecubes normally don’t allow 480p either. To answer the second part, connecting audio via the composite cable works just fine. And you actually have to do it that way for the official component cables.

I think a lot of people end up using line2x on 480i/576i because it’s the one mode their TV will accept. Support for 480p is pretty much universal, but there are lots of displays and devices that don’t accept 480i/576i over HDMI, even though it should be perfectly fine; plus, there’s an issue with some metadata or flags when using 480i/576i that’s fixed with firmware 0.84 (which I don’t think is out yet), which can cause incompatibility with passthrough (Happened to me with my Onkyo AVR; happened to several mroe with Denon AVRs).

If you’re still talking about 480i/576i, there’s no line5x available for those modes; and a lot of TVs (especially 1080p and smaller-resolution models) don’t like the resultant 1440i/1728i or 960p/1152p modes, because they’re not HDTV modes (and they probably have funky refresh rates). Sometimes you can get a video processor, like the Extron DSC 301 HD, which can handle them, but TVs usually won’t like them.

If, instead, you’re talking about 240p/288p, the problems are similar; you probably have a picky display. (Also, the manual says that line3x/4x/5x don’t generate standard modes that may not be accepted by consumer TVs.)

Thank ou for the replies!

Yes I have a component cable for Wii U. The Samsung adapter YUV for my TV is a chinese copy (I lost the original one), The quality is a bit worse. The quality betweeen ma GC RGB and Wii component is more or less the same (there is only a difference of color/brightness). That’s why I wanted to try if I could get a higher quality with OSSC

Last week I tested the homebrew Game Boy Player (GBi) on my GC in 240p with OSSC x2 and x5. The quality was perfect! It looks like my TV accepts these modes in 240p.

And you actually have to do it that way for the official component cables.

In fact I got it many years ago (I didn’t know at this time they were expansive) but I’ve never used it because it was a D-Terminal connector. I found a D-Term to cinch only last year and I tested it quickly.

Today I tried to connect my component cable for GC to the OSSC but I don’t understand how to connect the audio.
There are 2 CINCH cables for left and right audio. OSSC has two inputs jack 3.5mm (by toggleling a switch)
Are they the correct way to connect the audio of my GC ? So I need a CINCH to jack adapter ?
Note: the question is the same if I would like to connect any other component cable (ex: for Wii or Ps2)

Thank you

Yes, female RCA (cinch as you call it) to stereo male 3.5 mm is what you need. Cheap, simple.

Thank you!

This will not work. PAL Gamecube games will not output native 480p unless you force it with Swiss. The Gamecube can output it, just like the Wii, but its the games themselves that can’t, without using Swiss. Deinterlacing / line doubling is the only option. I only recently realised this as its quite confusing and a lot of people don’t know about it or assume everyone has NTSC / Japanese. Let me know how you get on with the OSSC though cause I’ve been thinking of buying one to improve my PAL Gamecube’s 480i & 576i (for some games, particularly annoying) but don’t know if it will actually improve them or by how much (all the settings on OSSC intimidate me a bit). Anyone else know?

[Nico128]

Hi. What will not work ?

. Let me know how you get on with the OSSC though cause I’ve been thinking of buying one to improve

Yes, what do you want to know ? I have a official componant cable for GC and I’m also able to run Swiss.

This is correct, it’s a limitation with PAL software no matter what console they are played on. Basically, Nintendo were lazy and just replaced the 480p option with 60hz for PAL software.

I’d recommend getting NTSC copies of your favourite titles if they aren’t overly expensive.

[marcusfrewinridley]

Ah OK I missed that you had Swiss, then you should be able to force 480p with most games no? Unless Swiss runs on Wii as well (I don’t actually know weather it does or not) then PAL Gamecube games will not run in 380p on a Wii, only 480i / 576i for some. Why go down to 240p for the OSSC to scale it back up, is this just the best way to get higher than 480p?

As someone who doesn’t want to run Swiss, I’m just curious if the OSSC can improve a 480i or 576i picture with any of its settings (I don’t fully understand them, I guess it’s scaler, the 2x, 3x etc.) as that is what I am stuck with (as a PAL user)

[BuckoA51]

Swiss can force some (maybe all now?) PAL games into 480p but some may have glitches.

Of course, Swiss is improved all the time, so it may only be a trivial amount of games that now have issues running at 480p.

As for your question, it depends on your target display and your definition of “improve”. If your only criteria is reducing input lag, OSSCs deinterlacer is the fastest possible. Generally though, you will get better picture quality by using passthrough and your displays deinterlacer.

[marcusfrewinridley]

More interested in the picture quality than the input lag, so the upscaling I guess, just not sure how that works with OSSC?

There are some PAL games like Luigi’s Mansion and the Maio Party games that only run in 576i, not 480i, so can only be 576p not 480p even with Swiss as far as I know. Not that sure how Swiss works either though but I guess you can just get the NTSC game files?

[nmalinoski]

If you can’t successfully force the PAL Luigi’s Mansion to 480p and decide to use the OSSC to handle things, the default will be to bob-deinterlace the 576i to 576p, which will be passable, but won’t look good, and bob-deinterlacing can cause image retention issues on certain types of TV, like OLED. Alternatively, you can try to switch to passthrough in the 480i/576i proc menu to let your display do deinterlacing.

[marcusfrewinridley]

OK, so the OSSC can’t upscale 576i, only 480i or 480p?

[nmalinoski]

I’m pretty sure I directly said that the OSSC can make 576p from 576i, and that it does so using bob-deinterlacing. The same goes for 480i->480p and 1080i->1080p.

Strictly speaking, no, the OSSC can’t scale in the sense of taking any input and transforming it to any arbitrary resolution/framerate, nor can it deinterlace or perform any other image transformations, because it lacks a framebuffer; it only has a linebuffer, so it can only output multiples of a given line, such as line-multiplying 240p 2x, 3x, 4x, or 5x to get 480p, 720p, 960p, or 1080p/1600×1200/1920×1200 or applying per-line transformations like scanlines. The OSSC Pro, which is supposed to arrive later this year, is supposed to have a framebuffer and be a proper scaler.
