I guess they reverted to the old crl because of the warnings generated by the additionnal words added for dead time checks.
I added the tag so that those events are ignored by the fastbus decoder :
dt2 = Read3800(0xab8000,1); -> *rol->dabufp++ = 0xfabc0003; *rol->dabufp++ = 0xdeaddead; *rol->dabufp++ = dt1; *rol->dabufp++ = dt2;
Replay seems happy again now.
