Hi, the ideal would be to have all the games in all versions, but quite a few people scan and share them, even though retro games sell a lot.
I hope someone with games from that region scans something and shares it. If not, you can always include the German letters in any other available version. Although I don't know if there are many more differences besides the text.
Best regards, and good luck with your search. If you find it, don't forget to share it here.
