don't know, i usually just stick to the NES resolutions and per single screen, but maybe for pan & scan sprites, maybe i will in the future, in fact i should say, i forgot to crop the picture and create the transparency (and since the situation here when i live is still quite problematic...............for not saying chaotic, i don't think i could work for a while).
but this is my 1st decent job at this try, and i will told how i did it, instead of redraw the image pixel by pixel and reinterpreting the image, i just paste the original in the NES screen template, reduce to 64 colors, and then doing the color reduction manually, and remove the garbage pixels, and rework some of them, and reduce the damn thing to 13 colors, It's not really hard, at least not this one
