Anyone know where quarter arcade gets the rom's from to run checksums?  I am
finding a couple of different versions but not all of them appear to be on
QA.  There are 3 versions of kick / kickman, and only two appear on QA.

I used freshly generated signature tests on an Exidy Ripcord earlier 
this week and the sigs were all correct.

The sigs are based on the MAME ROM images. If there is a problem with 
the archive, or they are a different revision, then your results would 
make sense.
