... I cannot launch anything through bootcode.dsi, since this file is completely ignored (?). So, I can't install HiyaCFW or DsiMenu++ anymore. Why is this so strange behaviour happening? Maybe the .tmd in the NAND can't be modified anymore? Is it right-protected? But that should not matter ...

... of one tile, then? Yeah, the glitches are mostly 8x1 sized, and some look 16x1 (that seems a little fast for consecutive register writes though?). Why would writing during hblank corrupt the sprites? During hblank the PPU is fetching sprite pattern data for the next line. So to be more precise, ...

... because they hadn't bothered to clamp the output of the blender, on the grounds that alpha blending with clamped sources can't overflow. This is why glow effects sucked on the N64. Also, with alpha blending you still have to worry about what you're blending it with. The SNES could do exactly ...
