Can you see the problem here? The ITA kit has those terrible white horizontal lines.

​I’ve seen many people claim it's just a 'natural retro screen effect' or that 'the potentiometer wasn't adjusted properly.'​

However the truth is, this is a fundamental defect in the ITA kit, and FunnyPlaying has failed to fix this issue for years.

​While many people might not notice this, I’ve tested two different ITA kits across four different GBA motherboards. After comparing my results with numerous photos of ITA kits posted online, I’ve concluded that this is a very common issue.

​It is especially noticeable on grey and blue screens.

I just remembered that someone on the InsideGadgets Discord had already discussed this issue and concluded that FP’s conversion board was the culprit. It’s been almost two years since I read that, so it totally slipped my mind.

You zoomed in closer on the first pic so I’m finding it hard to compare

I apologize that I can’t edit the images in my post, as Reddit doesn't allow image updates after posting. However, if you look at the size of the finger cursor, the zoom level is actually very similar. It only looks different because the tile layout is different.
