Does it matter? Don't they just update the firmware?
This is great news! I love my NES version
edit: why would someone want the "none" option for the lockout chip? - never mind, I read on the site, it's for clones
edit 2: I see that the incompatible games are the ones that rely on extra chips. Will they need to actually install new physical chips in order to make these games compatible or can they just use software upgrades? I'd like to be able to play Super FX games.
