I only have 5 games for it so far though
The games that are complete with box and manual are Metroid, Castlevania and Nazu no Murasamejou and the two games without manuals are Kinnikuman and Donkey Kong Jr and Super Mario Bros in one.
My two favorites are Metroid and Castlevania. And it’s really fun to look through the manuals which have a lot of artwork.
Here are some pics from the Castlevania manual
