# 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. 9D/9E).
|
|
|
|
# The returned value has the format SSGGRRVV, where:
|
|
# S = 33 (which represents PSO GC)
|
|
# G = game (4F (O) = Episodes 1&2, 53 (S) = Episode 3)
|
|
# R = region (45 (E), 4A (J), or 50 (P))
|
|
# V = minor version | 30 (30 = 1.00, 31 = 1.01, 32 = 1.02, etc.)
|
|
# 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.
