Jam Player

I'm attempting to load one cyclone (CA) from another cyclone (CB).

CB uses general I/O pins to drive the jtag pins of CB.

I've got a copy of the jam player software from Altrera.

I can access the jbc file and decode most of the data.

The calculated CRC noes not match the CRC saved in the file (that's curiously 0x0000)

My questions are:

Has has anyone got this working?

Does anyone have the jbc file format?

THanks
