NeoGeo Online Collection Vol. 8 - Fuuun Super Combo (Japan) Native 240p [cold boot i.e. hold R1 when powering up PS2. you will enter ULaunchElf console. From there navigate to OPL. Game mode 6 (disable IGR). Note: If using OPL OPNPS2LD-v1.2.0-Beta, cold boot not needed. Just use OPL mode 4 [Skip FMV] and 6 [Disable IGR]. Doesn't work if forced into 240p using GSM 0.23 as it is not compatible with OPL OPNPS2LD-v1.1.0- or 1.2.0-Beta and skipping FMV only truly works in those OPL versions.

"Capcom Vs SNK 2 [tested with GSM 0.23]"

Interesting, I guess I need to try this version of GSM. What made MvC2 look bad btw?

I don't know firsthand, but doesn't MvC2 have 640x480 backgrounds? I imagine that wouldn't look so good downscaled to 320x240

But I don't know if that's why BigBoss didn't like it

Yes it has high-res backgrounds which dont translate well into 240p. plus the game uses billinear filtering to soften character sprites so they dont look too pixelated on HDTVs. Unfortunately billinear filtering cannot be switched off unlike some SNK games and that makes the filtered character sprites rather blurry in 240p.

This is something we've known for sometime but I never really delved into. So billinear filtering can be akin to the technique anti-aliasing (reducing pixels instead of jaggies). However, does this imply developers had in mind flat panel displays? Because not all 480i content is bad (i.e. blurry). Sometimes, I could barely make out if a game is 480i as it can look almost as good as 240p (e.g. Yu Suzuki Game Works on the DC). I read there are other methods used together with the mentioned technique such as MIP mapping which involve interpolation.

Does anyone know about other (better) methods for upscaling 240p content to 480i? Was trilinear or anisotropic filtering ever utilized? Or perhaps no filtering applied?

[Bassa-Bassa]

No filtering was rare (from N64 onwards) because they used it to mitigate interlace flicker.

However, does this imply developers had in mind flat panel displays?

A friend of mine I trust the most for these matters has some other theories which also make good sense, because flat panels were not the main display at all for home videogames back in the DC/early PS2 days - overscan and hardware discrepancies. When you're porting an arcade game with a native resolution bigger than 320x224 and keep it for the port, you're getting quite a bit of non-wanted overscan in many TV sets. This forced them to relocate the HUD in many ports for the 32bit systems, for example.

There's also the issue that not every home system could handle horizontal resolutions such as the 384 pixels of Capcom's systems. So if you just scale it up to 640x480 or 512x448 (and then just use the filter which better suits - for Yu Suzuki Game Works they likely just line doubled the graphics, so any light anti-flicker filter would likely do), the issue is solved, and very few complained then for the lack of 240p. The DC case is also special, as devs were kind of compelled to always include a 480p mode for VGA output (intended for PC CRTs, not flat panels), so a universal 640x480 frame (which I believe it's actually 720x480 with an active area of 640x480, precisely to avoid overscan issues) was the easiest solution.
