macOS Take intel app and convert to UB.

[Joshuarocks]

Hello.. I have Xcode 3.1.3, xcode for use with Leopard.. I want to take intel only apps and make them universal binary.. get them to run on PPC to help support the developers out there dedicated to keeping the PPC platform alive.. How do I, for instance.. convert a mac app from the app store, such as Hands off! for universal binary?

Is it like a switch I need to switch on? Also, if I can disassemble the code for that program, can I then make it into a universal application?

It is not possible to create a universal binary without the original source code, and even if you had the source code it is highly likely that apps written for Snow Leopard will use APIs that are not available at all on PPC.
