I'm not an expert on this issue, but it really depends on how these rebuilds are made. If they are recreating the code and just adding a "emulation" layer then yes they will have an overheard in each game. But if the game is rebuild for the new hardware from the ground up, then there is no overhead at all in the same sense that a arcade to snes port didn't have an overhead
Yeah, if they are recreating the exact code by compiling comparing to the original binary blob, they are getting quite a close to truth source code that can be complied for other systems without any burden of emulation mixed in there.
