About rare SCI games:Brasoft versions of Leisure Suit Larry 5 and 6 are in the Brazilian magazine PC "
Multimidia" #6 and 11, but I tested both games and they are in English only. So I don't think there is a Portuguese version.
I found Leisure Suit Larry 5 in Italian and it's an official translation I think. But the Interpreter doesn't appear with Sierra Version Tool:

On the other hand, the official German version of EcoQuest 2 has been unearthed:

Personally I'm desperately looking for the Japanese versions of:King's Quest VII / キングスクエストVII / キングスクエストVII (PC Windows)
Lighthouse / ライトハウス (PC DOS/Windows)
Phantasmagoria 1 / ファンタズム / Phantasm (PC Windows)
Police Quest: SWAT / ポリスクエスト SWAT (PC DOS/Windows)
RAMA 宇宙のランデヴー (PC Windows)
Shivers / シバースー ~呪われた博物館~ (PC Windows)
