I have multiman installed and everything seems to be working fine with the lvl 2 package. I do not launch the game directly, I launch it from the XMB. Haven't had any problems yet launching GT5 - NFSHP - Fight Night - Infamous - Star Wars etc...
Do I need to install dbemu.pkg can someone explain what's this for in ENGLISH please (Noob here)?
Starting in MultiMAN v01.16.00 the payload wasn't included for legal reasons, so when when running the BDEMU .PKG file (necessary the first time only) it will place the required BDEMU.BIN in the correct folder so that you can use nwer versions of Dean's OBM PS3 Mod.
If you are using older versions then you don't need it as it was already integrated.
Edit: Nice beating me with a reply bitsbubba and +Rep.
