Infrared communication was actually possible on the DMG with the HuC1. The difference was that Nintendo made it a standard feature of the hardware rather than a cartridge-based add-on, but developers definitely had the option prior to the GBC (though going Hudson's route would likely have been very ...

Er, wasn't the GB Micro just a low-budget version of the GBA for those who still wanted one when it was being phased out? Hmm... I was under the impression that both the SP and the Micro had a MSRP of $99.99 USD, and both were discontinued in '08, so I don't think it's a matter of price or phasing ...

I recently saw earlier this year a commercial for the Zelda and Mario Wii U deluxe where there were kids in front of the TV...thinking of ways to get their parents to buy something. Whenever there is a new build or even a promotion, Nintendo takes advantage of the children because they know that's ...

Why even create a system such as GB Micro? Nintendo has a long history offering different iterations of their hardware, much more so than their competition. In part, it's a move to drive profits, but it's also a move to appeal to gamers who were interested in ultaportable handhelds, or at least fou...

A problem I have with Nintendo (both in Japan and outside of Japan, actually) is their systems sometimes become incompatible even if otherwise mostly compatible, even in NES, Nintendo removed the CIC causing their own cartridges to stop working, AV Famicom removed the microphone, DSi removes the GB...

You can "cheat" your way around HW sprite limitations if you DMA data to OAM during HBlank, however, this is more easily done on the GBC rather than the original DMG, since double speed mode allows you to calculate anything you want in half the normal time, and HDMA are really handy withou...

@tokumaru - Those distortions aren't applicable to every scaling filter. Scale2x in per-layer and per-frame produce almost identical results. This is most likely an issue with how HQx detects patterns. We haven't even examined other methods like xBR. It's premature to jump to those conclusions, not ...

If there were a hybrid method, I think that would produce the best image quality in terms of anti-aliasing and color smoothing. Certain smoothing I like in both methods, but have parts the other seems to improve. If you do implement this in your emulator, I still suggest using the GPU for HQx scalin...

Much better : http://i2.minus.com/ixSEX35IudDi4.png So far, the best attempt yet. The weird angling on her hair and shoulders are not nearly as noticeable as before (though I can still see it). The only other thing that comes to mind is that the anti-aliasing when doing it per-layer isn't as strong ...

Using the new code you posted + the masks you used : http://i5.minus.com/iuEGTvdXO7gc1.png

Closer but still neon-like, unfortunately.

Are you it isn't this instead? ->
MASK_1 = 0x000000FF
MASK_3 = 0x00FF0000

If I change my masks to be your masks, I get the neon effects again:

Most major compilers today should interpret a signed right shift as an arithmetic right shift. It's still very much implementation defined, but as far as I know, it's a pretty wide-spread one if you factor in Visual Studio, GCC, ICC (Intel), and MinGW, at least as it concerns x86 platforms. So if we...

Speaking of issues with using HQx on separate layers, the slimming of Shantae's shoulders (and the upper-left part of her hair) is annoying, and I don't think it's related to the problem of transparency. If you look at her hair specifically, it keeps shaping it into something like a staircase. The s...

Yeah, it looks like aSum could be zero in some cases, and there's no check to stop the division. I still can't figure out why I get the neon colors I referred to earlier. It's almost like anything that isn't edge detected is filled with black. Anyway, what I said earlier about the pixels not being t...

@mkwong98 - The Pastie you posted doesn't compile (the pointers are new code since it changes some function definitions) so I couldn't copy+paste the entire common.h you linked to, but just taking the code inside Interpolate_2() and Interpolate_3() compiles just fine. This is what I used: http://pas...
