Chess on Kobo Clara?

Hello, I have been a happy user of the excellent pbchess by vlasovsoft on my Kindle until it broke. I bought a Kobo Clara but found out pbchess is no longer supported. (tried it, it crashes at startup, switches off backlight, requires reboot)

Does someone know how to make it work?

Or, how much work would it be to port existing software to the Kobo environment:

- porting one or more chess engines (Stockfish, CuckooChess, etc.)
- porting a chess GUI (cutechess - it runs on Qt, other?)

Thanks!
