+ * Chrono Cross CD extractor Copyright 2000-2001 by Yazoo (hamm@efrei.fr) Revision 0.1b ANSI C
+ *
+ *
+ * Features:
+ *
+ * Dump the complete content of Chrono Chross CD1/CD2 US and Japanese version It requires a iso
+ * named Chrono1.iso in the same directory
+ *
+ * Todo list:
+ *
+ * Find a way to locate end of the last file Better support for CD2 Dump in subdirectory according
+ * to CD1/CD2 repartition Recompilation in Visual C++ 6 for disk speed optimisation Source comment
+ * and reorganisation Log feature (Optional since you can redirect output with > ) Progression
+ * indicator Better detection of the ISO with error control Major code optimisation Integration in
