[Mobhack]

1) Black and white - use the PSP tool to make a greyscale image of your JPG. I cannot recall - but it is on the menu. (I do not have PSP any more, and last made an LBM a year or more ago). Then save the JPG as a B&W, use it as the base for LBM conversion.

Actually - best to save as a PNG as that is a loss-less compression, whereas JPG is a lossy compression, so converting a JPG and saving again as JPG has added more "loss" to your process.

2) LBM Palette - see the PSP help about how to extract from an existing LBM, and extract the palette from one of our B&W LBM. Save that, ansd use as your LBM palette in any future work. See the PSP help file for details. You must have the correct LBM pallete, or you will see a smear of mush in the game (but not in Mobhack).
