Last month (May 2019) an English translation patch was released for Pichu Bros. Mini. This was the last of the 5 Japanese-exclusive games to get a fan translation, meaning every game in the Pokémon mini library can now be played via emulator, or using the DITTO mini flash cartridge.

This fan translation was a collaborative effort between users Mr. Blinky, YasaSheep, snesy, and NikcDC

The translation can be found here.
