No, I can't manipulate XMB options, severusx.
Ok, it is ready... The good thing is that if other MANAGER developers decide - they can make 'lastplay' to work with them, too (like gaia, rogero, etc)...
The app requires a simple text file saved as
with two lines (at the moment), but I may add other params like (patched mode):
SELF=<full path to EBOOT.BIN>
PATH=<path to mount /dev_bdvd>
The app on the xmb will show all game props like game icons, background, movie icon.
