Hacking Mac OS X (PPC) Apps

Over the past couple day's I've taken to hacking various trialware Mac OS X (ppc) apps. It's been quite the experience, especially since I've never before seen PowerPC assembly language.

The tools of my trade are otool for disassembly, code-dump for decompilation, and 0xed for hex editing. Maybe I'll write a quick guide on how to do it.

Successful hacks so far: Color Schemer Studio and Gordon. All I had to do for both with switch a conditional to branch if the opposite condition was met, i.e. instead of registering the product when the serial number is correct, it registers when the serial is wrong.

Unsuccessful: Acquisition. Great Job, David Watanabe! He's probably had experience with people hacking his program, and has figured out ways to prevent it.
