I’ve read about nice utility to extract rom.zip from RUU update and could not believe someone really have spent time to write a program, which might be easily obsoleted with new version of installshield.

Here’s a quick and dirty, but very reliable approach which does not care about installshield version and relies only on expected file name (rom.zip)

1. install wine
2. open terminal and change directory to .wine (cd ~/.wine)
3. in the terminal type (but don’t press <enter> just yet) : cp `find -name rom.zip` ~/
4. run RUU update file in another window and change back to the terminal
5. as soon as the progress bar reaches about 70-80%, press <enter> in the terminal
6. enjoy rom.zip in your home directory (but don’t forget to check zip integrity and checksums just in case)

Worked for me as a charm and did not require any 3rd-party software.
