SEGA's SH2s have "extras" for 3D graphics calculations, CPS3 will not touch that I suppose. Besides that it's the same SH2 as all the other chips.
Some SH2s have additional rom space as well.
I think we'll never know until someone will RE specific chips.
it's also might be one of rare used or undocumented features, for example JTAG, Sega may want to change it, to make it not possible to debug / hack its devices using existing JTAG debug adapters.

hmm, which kind of 3D extras may be in SH-2 without FPU?
KiCADs for the multibios helper board are attached, had some requests to share them - this doesn't currently work for me.
I dont know if my implementation is bad or if my manufacturing is bad. So use at your own risk
But at least the physical layout is good
Also some questions from @chacal231077 about SMD latching switches - which I actually cannot find any of... zillions of SMD momentary, but not many SMD latching... Anyone got a good source?
