+# This function returns the game version, with values more specific than can be
+# detected by the sub_version field in the various login commands (e.g. 93/9D).
+
+# The returned value has the format SSPPRRVV, where:
+#   S = version (31 = PSOv1, 32 = PSOv2)
+#   G = game (4F = PSO)
+#   R = region (45 = E, 4A = J, 50 = P)
+#   V = minor version (31 = NTE, 32 = 11/2000, 33 = 12/2000, 24 = 01/2001,
+#       35 = 08/2001, 46 = not a prototype)
+# This results in a 4-character ASCII-printable version code which encodes all
+# of the above information. This value is called specific_version in the places
+# where it's used by the server.
