In-manager options-editor requires some work and I'm not really in the mood, but may be I'll do it after so many requests.
Yes, multiMAN sets proper attributes to all files it copies, that's why you see them on your PC (not hidden as comgenie's fm).
is the test version of multiMAN + LAST_GAME application. Install both and test it.
There is a problem (of course) because PS3 won't update its internal cache when a PARAM.SFO is changed, which causes troubles. How it works:
1) You start a game from multiMAN
2) File is created for LAST_GAME application
3) Depending on "Launch directly without going to XMB?" question result the LAST_GAME will be set accordingly.
4) The next time you reboot your PS3 you can launch the last game played from an icon on the XMB. If the game was set for "direct boot" (in step 3) it will start directly, otherwise it will mount to /dev_bdvd and /app_home and the app will exit. Then you must start your game from /app_home or from a disc.
5) The 'last game' app will get the original param.sfo (+some changes) and original game background pictures (pic0/pic1/icon0/icon0.pam) + the animated icon.
6) If you launch the 'last played game' application and the path to the game is not available (for example when you used a game from USB drive and it is not connected), the app will exit and restore its icons and param.sfo.
Dean p.s. Parsing between multiMAN and 'last-game' app is done via simple text file:
SELF=<full path to EBOOT.BIN>
PATH=<full path to game folder>
USBP=<0 - disable usb patch mode, 1 - enable patch mode>
BOOT=<0 - mount the game and exit to XMB, 1 - mount and start the game, without going to XMB>
