Hello Martin,

I read in the Wiki the Millennium Schachpartner 2000 (Kaare Danielsen program) relates to the Yeno 430 XT.

I could not either find this manual, but the Yeno 430 XT can as well be found rebranded as Lexibook Chessman Elite. Many Lexibook devices share the same or so manual.
So, maybe worth checking if these manuals would fit:
- english
- french

Are the level settings similar?

Hope this helps,
Gruß,
Eric
