Nicolas,
I just compiled Hatari with the updated English and French lproj directories. Hatari does compile and I see the Info.plist file inside the bundle. I would say you could update these directories and the OS X version will compile.
Jerome,
Thank you for the information on the manual XIB compile. I was trying to automate the compile in the Xcode project. In the current Xcode version (4.6.3), the XIB file was listed as a resource but it was only copied to the application bundle. It was not compiled to an NIB file. I was just wondering if you put the NIB file in a different place in the project to get it to compile or whether you did something to either an Xcode preference or a build setting to make it compile the XIB file.
When 1.7 is released, I look forward to seeing your Universal Binary. I am very hopeful it will be uploaded to Tuxfamily by the time I get back from holiday in a couple of weeks.
