they tried otl but masively misfire with the dual CPU, your ideas more sensible is what they should have done(plus the SH have similar function the RISC MIPS sony use, the matrix sum-multiplier was something mandatory for 3D, as vectors are matrix itself...i learned a lot for my tl,) AND something sony reminded to useSEGA’s motivated to outdo Sony (might create an ATL comer so the Saturn probably has a matrix sum-multiplier somewhere (prob in the GPU).
Yeah the N32 is far more elaborated and pretty well done, waiting next chapter
