TG,
The installation of an emu in any image i had is just copying the program files to var/bin chmod 755 and the key files either to var/scce or var/keys depending on the emu.
What is different from image to image is the way to make them available in the emulist.
For hydra images i posted a mini tutorial for camd3 manual installation at
http://www.sat-industry.net/forums/s...ad.php?t=19912 but you can follow the same procedure for any other cam as far as i know(Tried newcamd, scam and xcam)
For ruDream the difference is that you edit emulist.xml file but it has been a while since i stoped using their images so i do not remeber exactly where that file is located. (You can ftp all of the files to your HD and do a search there). The only thing that has to be added is a line like for other emus there.
Now i just flashed the new SDT image but i didn't have time yet to check for manual installation of emus. I only update the program files with the new releases(ftp)
Hope this helps.
