I've seen that issue before, but thanks for bringing it up. I think the problem isn't so much that HQx can't generate transparent pixels (it can) it's just that what transparent pixels are there aren't transparent enough. If we could make the problematic pixels outlining Shantae in my example much m...

That commit doesn't not use the alpha value to calculate the interpolation. For example when the weight of the two colours are the same, it does the following: It's inaccurate to say it doesn't use the alpha value in calculations during interpolation, since it does just that http://code.google.com/...

Actually, HQx does support transparencies. This was the commit: http://code.google.com/p/hqx/source/detail?r=10 That's what the whole MASK_ALPHA is doing, so alpha transparency can be taken into account. You can try it for yourself. Here are the two images I generated with HQ4x for Shantae. If you t...

@mkwong98 - All I did was take three screenshots of Shantae, one with all sprites disabled, one with the background disabled, and one with both enabled. For the screenshot with the BG disabled (the one only showing sprites) I removed the background in place of completely transparent pixels. For the ...

If the end result is better, what they were originally designed to do shouldn't matter. =) But the end result isn't better, or at least no one's devised a good enough result separately applying scaling filters to different layers. That certainly is the easy way out, which is probably why most emula...

Isn't that the idea, though? Different layers aren't supposed to blend together. I'm pretty sure that the background causing deformities to sprite outlines (and vice-versa) is a good thing to avoid. To my knowledge, none of these scaling algorithms was designed to work with pixel data as separate l...

BTW do these scaling algorithms work better when applied separately to each layer? I would guess not. If, for example, you applied it to sprites separately, the edges probably won't blend well overall with the background, but the effect would be interesting to see. I have never tried to apply somet...

Totally glad I wrote this last year: http://6bit.net/shonumi/2013/04/10/in-depth-scale2x/ One of the most annoying things I find about pixel scaling methods is how poorly they are documented, with the exceptions of ScaleX, Nearest Neighbor (and maybe Bilinear?) and xBR. Just about everything else ex...

It's an Intel ATOM N2600 dual core with hyper-threading; No, it isn't pegging it uses around 20% of cpu time on this ATOM CPU. Is that too much?? Honestly, it depends. What do you, as a developer, feel should be the lowest hardware you will support. Do you want yanese to run on things like low-powe...

@Myask - That's the point I was making. For your average user, the FCEUX port is complete enough. It's those extra features that are actually pretty niche even as far as emulation goes (TAS and debugging). Most people involved in emulation just want to play games (myself included as it regards the N...

Only a handful of Mednafen's cores are actually original (and some of the code for a few was based on existing code/designs, whatever the truly means). NES emulation is provided by FCEU, though I'm not entirely sure which version it currently uses. It's probably not hardware-accurate, but "accu...

Arguing with Internet fanboys helps me discover my own hidden denial of evidence. I'm simply saying that with fanboys, it's hard to get anywhere, and all bets are off when it comes to having decent discourse. Getting into lengthy, irrational, impassioned "discussions" where the opposing s...

Yeah, but that seems to be slowly changing lately (albeit more from the hand of the smaller developers), so if that ends up panning out in the long term that argument won't work anymore. Also JRPGs really don't appeal that much to the West, so that also makes it kind of a pointless argument... you ...

I want ammo against some of the "PC master race" people who inhabit a couple other message boards. I can't comment on cross-platform games for Sony and Microsoft, but if you want ammo against "PC master race" types, look no further than the dearth of JRPGs on the PC compared to ...

The GBA wavetable could be banked as well, resulting in 64 4-bit samples if the programmer desired.
