yohoho.log is the debugging log file for the Puzzle Pirates client. It is a simple text file, loosely formatted with precise time-date stamps, priority levels, and freeform log messages from the Java code. It also includes stack traces when an uncaught exception is thrown. The file resides at the top level of the client directory or folder. The active client's debug log was previously written directly to "yohoho.log", however, recent versions of the client write to a file in the format "yohoho_NNNNNNNNNNNNN.log". Old log files are still renamed to "yohoho-o.log"
