Various of these Tiger LCD Handheld games have been released in Brazil by TecToy as the series "Minigames TecToy Série Master"
I think that for most of cases it's only localizations for the Tiger LCD games, but there are some exclusive titles such as Cebolinha, Mônica, Chaves, Senninha, Chico Bento, Xuxa no labirinto da Mocréia, among other titles based in popular Brazilian characters

While I think that these may be hard to find in other countries, they're relatively easy to find at MercadoLivre (Brazilian ebay counterpart)
