Hi all, Android Chess uses the GNU Chess version 5.07 for the Artificial Intelligence. This version has been compiled and tested for JXD S5110, but it should also work properly for other ARM based tablets or consoles. How to use it ? Everything is in the README.txt file. Sources are included, and this package is under the GNU public license, read COPYING.txt file for more information about it. See http://zx81.zx81.free.fr Enjoy, Zx.
