>>53249752There is no ability to buy old Nintendo games for any older Nintendo system, bar buying NSO and the expansion pass to gain access to the emulators. And Nintendo themselves said they would not be putting older games on sale in any capacity on the eShop.
>>53249786Firstly, it depends who holds rights to the games in the first place (I'd suspect Nintendo retained all rights to what was functionally their exclusive games). Secondly, that's clearly not the case or they wouldn't be shitting the GB emulator out in the dying years of Switch (Nintendo themselves said they foresaw Switch's lifespan to be about 7 years), given Pokémon is one of their biggest IP's by both revenue and by systems sold per game sale. If Game Freak were getting a cut of the subscription, they'd have gotten the GB emulator out in the first wave and had Pokémon as a launch title, to get 5 years of pokétard subscription cuts to bulk out the bank balance.
