Not always, the mister would need more elements to do an actual 1:1 for many newer consoles and the cores are often reverse engineered best guesses and not replicating the original asic design.
On the other hand, original hardware goes through revisions and the silicon can change (snes 1chip vs 2chip for example) while still be perfectly compatible so it really depends ho much of a stickler you are.
