Hi @howpeter, for your box you do not need files with ppc or sh4, but only mips. And here are the places to put them manually with DCC:
Mgcamd-->
Binary-->
mgcamd,(newcs)-->/var/bin (chmod 755)
Key Files-->
SoftCam.Key,AutoRoll.Key,tps.au-->/var/keys (chmod 644)
nagrarom7.bin-->/var/scce (chmod 644)
Additional Files-->
ignore.list,priority.list,replace.list-->/var/keys (chmod 644)
Config Files-->
mg_cfg,(newcamd.list)-->/var/keys (chmod 644)
Regards, Renard
