PSA: Do you have a DS/DS Lite/DSi etc. that can run homebrew? Do you have many? Do you have any with worn out touchscreens?
If so, you can help! I'm writing a new touchscreen driver for BlocksDS and want to test its behaviour on a variety of consoles. I'm worried I made it a little too complicated ^^ (I had a DS Lite with particularly noisy input, but this turned out to be exacerbated by a poorly applied screen protector.)
Press RIGHT once to show the "Adjusted input" mode on the touchscreen, so you can see your touch input being tracked as you draw.
Take note of the Z1/Z2 values as you glide along/adjust stylus strength. In this build, they are repurposed to refer to the amount of noise on the X and Y axis. (For example, on my worn DS Lite, the difference is <10 samples, while in a specific area on the left border it goes up to 15-20 samples. For context, ~15 samples = ~1 pixel of noise.)
