PSP-2000 Original Boxstyle Box Codes (Thanks to Alek @ Dark-AleX.org):
(No Letter) = 3.60
A = 3.71
B = UNKNOWN
C = 3.72
D = UNKNOWN
E = 3.80
F = 3.90
G = 3.95 / 4.01 (TA-88v2 / TA-88v3)
A PSP with G and the 4.01 firmware is most likely a TA-88v3 motherboard, so it is advised that you stay away from them.
