Don’t get!

The more games you get takes up all your storage, if you have 5 DS games then your storage is FILLED up and even if you delete it you will still have no storage even if you delete the the files

Two requests

Please have the n64 games use expansion pak because I wanna be able to play sm64 last impact, and add a select game option that doesn’t open the games you select so you can delete games that freeze or crash the app.
