[qacjava]

Hello!Friend,
I‘m a Chinese，My little daughter loves this game so much.
When I use nxengine-libretro of Retroarch (Emuelec) play Chinese Version .
but a few characters appear as black squares, or gibberish
The English version is very difficult for her now.

the chinese version download:

it maybe about the file named "Cave Story.rdb"?
but i don't know what kind of Datebase.
MySQL ? Oracle ? MongoDB ? PostgreSQL and so on?

pls help me !thank you very much.

It seems that nxengine-libretro supports only the english version.
