Being a fellow 9100 user, I'm interested in solving the signature<br>
problem too.<br><br>
I'm new to the TechTools list and I may be covering stuff you guys have<br>
been over before and be stating the blindingly obvious, but here goes...<br><br>
If the 9100 does in fact use a CRC algorithm, then there are only so<br>
many polynomials that are useful. As a start, trying out CRC-12, CRC-16<br>
and CRC-CCITT that are all 16-bit orientated polynomials might yeild a<br>
match with what the 9100 generates.<br><br>
As far as I know, the pods themselves do the signatures in the 9010<br>
configuration. Here, one would think a disassembly of the pod ROM would<br>
yield what we need or failing that a simple driver in MAME that runs the<br>
pod code would do the trick?<br><br>
