口袋妖怪-绿宝石/pocketmon-emerald" is just a hack of that Castlevania clone called Emo Demo or whatever the ROM was. Back of the box shows the main character(Raichu) in the same castle as in the original version, but the actual game has all graphics replaced, doesn't even look like a castle but rather you're outside all the time.
口袋宝贝-珍珠/Poketmon-pearl is a generic game based on the same engine as Digimon Yellow Jade, play as Meowth for a few levels, a boss, the end. Same exact music too.
