Okay guys, these saves work completely fine and there is no need to do any weird stuff. Save pops the Completion and Speed Comnpletion trophies ( not the ony for under 5 hours at the same time thankfully ).
What you need to do:
Download his save, when you oopen it with Save Wizard you see 5 saves, just resign the first save ( sce_sdmemory and the third save ( called save 2 ).
Important: Leave all the others saves be, the restore function messes everything up.
So as long as you stick to resigning these 2 saves everything works fine.
Cheers
