(Question) All in 1 DS Games

I recently became interested in one of those all in one DS video games. I saw some that have these obscure games I played as a kid (e.g Zhu Zhu pets), but not some of the more popular games on them that I want to try playing (e.g Pokemon). I have also seen the issue vice versa, where it has the popular games, but not the obscure ones. Any suggestions? (follow up Amazon has a 4,300 game cartridge without a list of games does anyone know what's on it?)
