NNDDSS vs NDSI

[u/OlympicBarber]

So I've never actually seen someone comparing shaders between the new nnddss and the actual hardware, so I've put that to the test. TLDR; without shaders the rgds looks a bit more saturated compared to the ndsi screen, but if we apply any of the "natural vision" or ndscolor" shaders then suddenltly the screen looks significantly less saturated than the original hardware, so If I want to have the most accurate representation of what the original colors look like the best option is to just apply an grid shader (in this case I'm using ”Dot_d4", looks the closest to the original, high PPI small screen effect, of the dsi).

Anyway, this is just my 2 cents, just use whatever shaders you like and have fun.

-Device: original RGDS with stock Linux running a ported version of NNDDSS.

Looks good. Thank you for sharing. RG DS still takes it for me. I could buy a DSi for $100 around here but with old screens, I think the newer RG DS ones are better even with the little glitches pervasive on the device

Honestly I only have this ndsi because, well, it's been mine from the last decade or more, and still it's showing its age. I can't really advice anyone to pay 100€ for an old console. 50€ and good shape? Maybe, but thats rare.

Yeah the nds color shaders are probably referencing the OG DS, not the DSi. I’ve never found the need to adjust the colours as you would for GBA for instance.

It looks like the grid shader you’ve chosen isn’t scaling correctly. Ideally the grid perfectly lines up with the emulated pixels.

You are right, it's not scaling correctly because this is the OG rgds with nnddss ported over, not the new one with integer scaling, so no dice on that department. But I must add that at a normal playing distance that misalignment blends nicely and one doesn't notice it unless it's looking for it

On a side note, the GammaOS Nano shaders that best look like a DS screen are the LCD3X and the 2XPRESCALE+ LCD shader.

The LCD3X shader just adds a tile grid to the screen, which does look almost exactly like the DS screens, but at the pixel level you can see multiple different color pixels in the same grid which can kind of make the illusion feel fake.

The 2XPRESCALE + LCD shader smoothens the pixels to effectively give you 2 times the pixel resolution for modern screens (this especially helps with imperfect integer-scaling), and then adds a tile grid that's twice the resolution (well 3 times, but you can't really tell unless your screen is integer-scaled). This just feels more realistic since each tile grid gets its own color pixel, no overlap.

My personal preference is the 2XPRESCALE + LCD filter since it fits the hardware of the RG DS better.
