The thing to remember about this, is that a future gc slot update on sysnand, may make emunand syscard slot not work until its updated, which may not be possible at the time. (whos using gc slot on emunand though....), This also applys if you try a new update on emunand, you could mess up your sysnand gc slot which would be a much bigger issue.The exception is the cartridge slot since it has its own firmware which is not redirected/emulated.
