I propose this patch for the Conic Computer Chess (cncchess2.zip) in order to respect rules of castling (black and white).
The problem appears in https://www.schachcomputer.info/foru...postcount=4729, by Franz (fhub).

Unzip cncchess2.zip, with a binary editor change old byte value with the new one (offset begin at 0) in the file c11485.u2 .
Rename the old cncchess2.zip to keep the original, and create a new cncchess2.zip with the modified c11485.u2 .
