Now on to the request portion of the post...

This is my first attempt at anything like this, and I've been having a bit of difficulty figuring out how to use these in a trainer.  So if anyone can point me in the right direction, I would appreciate it.  Note that most of these are inserting a return just after the function definition.  I was able to apply a these same changes directly on the file with a hex editor, but I would like to be able to turn them on/off on the fly. Thanks in advance...

Thanks for the info.  I wasn't able to make it work with Windows 7, but it worked great in a Windows XP virtual machine.  Flash player crashes in 7.  I'm attaching the cheat table for anyone who wants it.  Also, I had to use decimal values for the number of bytes, as opposed to hexadecimal, because it threw an error with the hex values (even when prefixed with 0x).

Here are a few additions as well:
