Luffier, Kindlevarazs
Thank you for your feedback and contributions! Nice job!
As for additional engines, they must support cross-compiling for ARM architecture. So far I was able to cross-compile five open-source engines, one of which (TSCP) was excluded, because it overloaded CPU and prevented normal update of e-Ink screen, and Phalanx was excluded because it worked extremely slow on Kindle. The three engines included in the build represent different trends in chess engine development. Crafty is a well-known 'reference' engine, Glaurung is the immediate 'father' of Stockfish engine, and Toga II is a descendant of Fruit. Actually I don't know how much difference Stockfish or Fruit can introduce on an embedded system. Anyway, if you know of a good open-source engine, that is worth a try, please post a link here. I will check if it can be compiled and if it runs smoothly on Kindle. If so, it can be included in one of the next builds.
