Now using BPEG to pack BSP maps would be utterly stupidity. BSP (Binary Space Partition) maps are used to optimize rendering and collision of geometry and has nothing to do with graphics data bitmap or other. As PBEG is lossy AND made for image data, it can not be done. Secondly the graphics in Jaguar Doom is not packed with BPEG, it has the same format as all other version 256 palette based rowbased with offsets for transparancy. The only fifference for the Jaguar is that the lookup table for lightning does not fetch the closest color from the 256 color palette but rather the exact truecolor value.
My own fair guess for why they use the Jaguar version is because it is the most Memory restrective. That is why the Jaguar version lacks alot of textures and has simplier level geometry.
