Yes. Component works fine on these interfaces. YUV in, YUV out and the deinterlacing trick works as well.

So GameCube, Wii, Xbox 360 and PS3 all have a "fake" 240p option then! Been looking at getting a 160xi.

GameCube/Wii output real 240p directly, nothing fake about it, no tricks/processing required.

Not on WiiWare games, which is the main reason I got the Extron. So it's useful for MegaMan 9/10, Castlevania and Contra Rebirth, and a few VC titles like the Arcade version of Ghosts 'n Goblins.

Gradius Rebirth is probably still best played in 480i/p, because even though the sprites are low-res, they move on a 480-line grid, which means they can be split between two lines on a 240p signal. Doesn't look very good.

Wii has the Virtual Console, and the GameCube has a select few titles like Megaman X Collection and Animal Crossing NES unlocks. What else is there?

I'm talking about hardware, not software.

For the GameCube, GBI is a popular application for 240p.

GBI is the bomb. I wish it was easy to hack WiiWare games into 240p.

So I got myself a 160xi off eBay. I've tried Wii Component 480i into the 160xi via a D-Sub 15 component adapter then connected it to my Sony PVM14M4E. What I will say is that I notice way to much flicker, even with the DDSP on or off. I know the YouTube videos for 240p from such a device use RGBs input, but for component I'd stay away.

It's not a problem with component. Your 160xi would look the same in RGB. Some Extrons are just not as good at doing the faux-240p effect as others. I bought a 480xi that's pretty much worthless for it.

If you throw the interfaces in one box with the actual scan converters, then yes, but if you compare one interface to another, they'll all perform the exact same way. After all the interfaces themselves don't do any type of conversion. They simply remove the half line offset on top, so the display will think it's progressive instead of deinterlaced content.

The results will depend on the type of game you're using. If you're using any game with true interlaced content, then what can you expect ? You're shifting lines onto each other that are not supposed to be displayed this way. Your result will be a flickering mess. But take a title that's originally been 240p and converted to 480i without any blur filter, then your results will be pretty much indistinguishable from true 240p.

I can reproduce that behavior with the OSSC. 480p output, though.

Scanlines = manual
Scanline str = 100%
Scanline alignm = ? (Top or bottom as necessary)
Reverse LPF = ~13
480i/576i proc - Line 2x(bob)
Allow upsample2x - on

but unfortunately it's only good because of the 100% scanline strength. The OSSC is missing a TINY field shift, which would make the result 100% identical to doubled 240p, even without scanlines. The XRGB-3 can do this. Unfortunately the OSSC's FPGA seems to be out of gates (or out of memory) to manage this.

I'm talking about games that should work, like Mega Man 9 on Wii. On my 201rxi, it mostly works, but there is weird effect, something like cross-talk between lines. Where a dark line will slightly shadow a bright line above it. And these lines seem to flicker a bit, which makes me wonder if the half-line offset you mention is misfiring at something like 5hz or 10hz. I can try to get a picture sometime to show the issue I'm talking about, since it's pretty hard to explain

And it might not only be on the extron's side, it might be some weird signal issue coming from the source, whether it's the Wii, PS2, Xbox 360, etc. Either way, I just can't get 100% legitimate looking 240p. It is close enough though, to where it looks better than the 480i from the source. I still plan on picking up another Extron sometime to see if I can get better results.

Agreed. I'm holding out hope for a custom firmware. Until then, the scanlined "fake line doubled 240p" is the best I can get out of the OSSC.
