Homebrew Pixel Error Checker ?

[Ralek]

Hi guys,

I'm searching for a simple app that let's you scroll through fullscreen red/green/blue/white/black to check for (sub)pixel errors on my nds. So far I just found some pixel fixers, but they all flash the color to quick for a closer look. LCD Tester by kleevah allows at least to hold black and white, but i'd prefered something like that just with holding the colors as well for as long as you wanna look at it. Really nothing fancy at all

Thx in advance.

Here you go, something I whipped together really quickly. Press A to switch colors and B to switch screens.

You can also try this. It helped me a lot.

Yeah, I know DiagnoSe has a pixel fixer, but I'm not entirely sure if it has what he's asking for. I've never tried it myself so I really don't know.

Ralek, my program runs fine in no$gba if you want to just see what it does. It's *really* simple but should work for your purposes.

And for good measure, since I was bored, new version that lets you choose the colors to display. I have no clue how to work the touchscreen so you must use buttons instead. http://www.zumodrive.com/share/zkCMTgwNW

When all are 0 you have black, when all are 31 you have white, anything in between is up to you.

@Rywiec Thx, I already tried that but liked I said the fast flashing colors arenot really suited for what I have in mind ^^

@DanTheManMS Thx again Dan I just tried it with no$gba and it's exactly what i wanted. Just one thing though is it normal that the screen showing the instructions is always flashing the writing ? Its kinda irritating ^^^ but otherwise, great work!

Flashing? It doesn't flash for me with no$gba 2.6a on both my (new) laptop and (ancient) desktop computers. Haven't actually tested it on real hardware so I can't say if it flashes on there or not. The program does clear the text and re-draw it every frame, but there should be more than enough time in the vblank period to write it. I'll try it on real hardware when I get the chance

No I just tested it on no$gba but something like 2.4 I think.

Works like a charm on an M3i Zero. Thanks alot. Totaly forgot to report back ^^

Not a problem, glad to hear it actually works. I never did get around to actually testing it myself, heh.
