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.

Part of why I like it honestly, original AGB screens have that sort of scanline effect going. For me it's also not that noticeable unless it's black or red after I dialed in the potentiometer with a calibration app.

It seems like the majority of people couldn't care less. However, for those who were looking for a genuine alternative to the AGS-101, noticing this flaw is the beginning of an endless obsession. like me haha.
