if it's true..great progress and they deserve a donation for the hard work
or it could be taking the piss like:
dex4.xx
game ripped to internal on 355/multiman
back to dex4.xx
insert original disc/bdemu+update
in the video u can see a disc loaded before loading multiman, but wich one... could be the original for all we know

he launches multiman(logo can be replaced)
launch DOA5 from gamelist- ask for param fix
back to xmb
and boots the original/bdemu from disc icon
heh me and my paranoia

hehe..let's hope it's real
