Btw, for the record...The original is located at position X=0, Y=0 and have a size of X=1200, Y=128
And the image you want to add should be located at X=0, Y=0 and it needs to have a minimal of X=150, Y=150 (im cropping it as an square because this is more convenient, it simplifyes things)
The image i made to calculate positions/sizes is ok... but i failed when looking at it and counting pixels
Your image should have size X=300, Y=300
And another btw... the black plane at back we was talking about is not needed because you said you want to use it in the gameboot, and the official gameboot already have a black background
