Sure, but anyone who's been playing these games on fan-developed emulators for literally decades at this point has been able to play the SGB-enhanced versions. It's frankly embarrassing that Nintendo has such a disregard for their own history that they can't include the full experience of games that were literally marketed quite heavily with these features in their day. The tech exists, fans have been doing it forever for Not $60+ a Year for years, and when they choose to do SOME things like putting all the stupid e-Reader levels in the GBA Mario 3 and not stuff like this, it starts to read like they really don't give much of a fuck.
