< p > - Updated March 22, 2004< / p >
< p > < br > < / p >
< p > The FCM file format is a somewhat "joined" file format. The first part of a FCM< / p >
< p > file will contain an FCS-format state save. After this data, the FCM-specific data< / p >
< p > begins, which is being referred to from this point.< / p >
< p > < br > < / p >
< p > < br > < / p >
< p > Currently, the only supported input scheme for a FCM is four joysticks.< / p >
< p > < br > < / p >
< p > The FCM data consists of a stream of joystick commands:< / p >
< p > < br > < / p >
< p > dLLjjbbb< / p >
< p > < br > < / p >
< p > d = Dummy update, if set. Used to reset frame timestamp.< / p >
< p > LL = timestamp length, in bytes(maximum of 3 bytes).< / p >
< p > jj = Which joystick(0-3).< / p >
< p > bbb = Which button(0-7).< / p >
< p > < br > < / p >
< p > If the dummy update bit is set, a command can also have occurred. Look at the< / p >
< p > lower 5 bits:< / p >
< p > 0 = Just a dummy update.< / p >
< p > 1 = Reset< / p >
< p > 2 = Power< / p >
< p > < br > < / p >
< p > The timestamp is stored after the joystick command, in LSB-first format. It is< / p >
< p > the number of frames since the last event. A timestamp length of "0" is valid, to< / p >
< p > be used when several different buttons need to change state at the same time(same frame,< / p >
< p > at least).< / p >
