Man, I do not miss having to line up these screens. Most of the kits I use now either go in custom shells or have nice brackets to position the screen, the GBA Hispeedido kit has these little plexi pieces where the idea is to push the screen against them and it's aligned. Except, it isn't, the pieces are a hair off, and you can't reposition the image in this kit. This is pretty much how the old IPS kits used to be, but I'm spoiled by Funnyplaying making things so much easier with their shells.
Anyway, I'm not done with my coworker's GBA yet, but I have it together and the screen with the pixel grid option looks pretty cool. It's a little dark with pixel mode on, but not overly so, about the same as a backlit SP. Only real snag is that with the display board's PCB sandwiched in there everything is a tad too tight and there are pressure spots on the screen. I'll have to review the installation to see if I can make a hair more room, I really don't want to have to leave the motherboard loose and make the controls feel sloppy. I don't think I'll be buying any more of these kits at least until someone makes a good 3d printed bracket or something for the screen, and I really hope Hispeedido switches to using flex cable sometime.
