I wrote instructions they're in the download, anyway I included them at bottom and a explanation of how it works.
1) Copy over the eboot and param.sfo from The.House.of.the.Dead.Overkill.CFW.Eboot.Patch.355 .PS3-iND (the BLUS patch)
2) Copy across the us directory in USRDIR.rar into BLES01326 USRDIR folder
3) Delete the uk folder in BLES01326 USRDIR folder
4) run in multiman works discless on external and internal
Basically what I did is I am still using the BLUS (US) patch, it works on BLES (EUR) version just by changing uk folder to us but a lot of text is missing. So i fixed that as well by taking the files from USRDIR/us folder in the BLUS release and putting them in the uk folder in the BLES release then renaming uk to us (so BLUS eboot can detect folder).
So basically to answer your question you're using the BLES release except one folder, the param and eboot are BLUS.
