For anyone running a Mac that's having trouble on patching the file here's what you have to do.
(remove the spaces from the links, i can't post links cus I'm new here)
Download Crizzle's Pokemon Outlaw ".ups" file
Download an unmodified/unhacked Fire Red ".gba" file (the one on doperoms*dot*com worked for me)
Go to this site and download the multi patch.
projects.sappharad.
com/tools/multipatch .html
There are instructions on the site but if you're confused.
The first bar is for the "ups" file
The second bar is for the ".gba" file
The third bar is just for where you want to save Pokemon Outlaw and naming it.
If you followed the instructions correctly you should have Pokemon Outlaw.gba or whatever you decided to name it.
I use Visual Boy Advance as my emulator and it works for me.
Cheers!
P.S.
Any update on the Emerald hack? Pretty excited and i'm sure it will be a great one as well. :D
