I recently decided to start converting my PS2 ISO's for use with the PS3 system; here you have a Command-Line GUI that I think is simple to use.
NOTE THAT THIS TOOL uses the same RAP key for every game it processes (the same one that PS2Classics GUI uses, so credit to them for all of the hard work over at ps3dev-network)
If enough positive feedback is given to this project, I will continue to enable BIN formats and add other changes...
What this program will do:
Create a PKG and RAP for your ISO
Pros: Can launch the game from XMB at any point
No multi-man required
Cons: Requires disc space (but you can use a game data switcher)
Requires installation of multiple RAP's
TO USE THIS APPLICATION:
1. Place your icons files inside of the Images folder
2. Run PS2iso2pkg.exe
3. Enter the PS2 Game ID
4. Enter the PS2 Game Title
5. Follow the On-Screen Instrucions
6. WAIT until all  processes have completed
7. COPY the "exdata" and "packages" folder to an external HDD
8. Install the PKG entitled with your Game ID
9. Install and run reActPSN (included in packages folder)
10 You're all good!

i should delete my ps2 xmb game and remake it use your program in this post (PS2 ISO to XMB Conversion Command-L) or nothing different between (CFW Eboot & PKG Resigner v1.20) and your program (PS2 ISO to XMB Conversion Command-L) ?..
the problem here when i go to Game from XMB and select "Saved data Utility (PS2)" can't see any save data ?! "Saved data Utility (PS2)" ((empty)) !!? but when i start the game from XMB still take ((LOAD DATA)) !!? it's mean there is save data but still can't find save data for replace it with my new VME ?!!!!..
I figured it out. I put the ISO file in the /iso/ folder and for some reason that's why it wasn't working (I removed the space beforehand and it still didn't work, but I shouldn't have spaces in file names anyway!)
Hopefully if anyone has this problem they'll find this thread and figure it out
