如果是没带memory的狗就是正常滴。以下是文件结构：
-----------------------------------------------
SafeKey's emulator uses its own *.FST data files for emulation (most likely the .fst is to denote 'FAST' or something similar), *.FST files are 138 bytes in length and have the following format :
{
dw seed1
dw seed2
dw modAd ; module address of supported Hardlock
db 128 dup(0) ; Hardlock memory (if applicable)
dd seed3 ; e.g. seed3 = 12EFh represented as 01 02 0E 0F
}
