So I wanted to convert a whole bunch of games to ISO for my Cobra CFW. I downloaded various versions of PS3 ISO TOOLS but I'm not 100% happy with it.
If I select a folder with 72 games in it, it hangs.
If a game is corrupted and can not be converted, it hangs (Does not listen to the return codes perhaps?).
If a conversion fails for some reason, I am left with a "CONVERSION IN PROGRESS" folder. I have no idea what game that is.

I am sure the problems can all be solved, but I noticed it all worked fine with genps3iso_v2.5.exe from a command line, so I just created an autoit script program to convert one or more games for me. 

The features are of course not as many as PS3 ISO TOOLS.

1: Select the source folder. This can either be one game or a folder containing multiple games.
2: Select the destination folder for the ISO. The ISO name will always be the same as the folder its contained in.
3: Select yes or no to the question if you want to delete the PS3_UPDATE folder before conversion. Saves a couple hundred megs per game and you do not need it.
4: Select yes or no to the question if you want to delete the original folder after conversion.
5: Select yes or no to the question if you want to split the ISOs into 4GB chunks (For FAT32 drives. Urk).

It'll then show you a list of all games that will be converted, providing you've selected more then one game.

While running, it will show the genps3iso_v2.5.exe window minimized so that any problems or progress can be seen, should you chose to see it.
Any errors will be shown with a message box. If you do not press OK on it, it will go away by itself in about 10 seconds and continue to the next game.
It will also log problems to a log file. No log file = no errors.

An INI file will be created to save the paths selected in #1 and #2 so it goes back there automatically the next time you run it. 
Autoit source is included.

Anyway, feel free to use this as a final resort if PS3 ISO TOOLS does not work for you, but do try that one first as it has a ton more functionality.
