Finishing Off The Complete Roster Hack

I have five questions about this patch:

• Can be used to add Leo as a permanent party member?
  
• It's compatible with FF6tools or FF3usMe?
  
• How do I install it?
  
• It's compatible with other patches and bugfixes?
  
• It's for version v1.0 or v1.1?
  

1. Yes. My hack, Divergent Paths, adds Leo, and a 16th character as well. The hack ReCast also makes use of it.
2. Yes. It is compatible at least with FF3usMe. I haven't tested with FF6tools, but I don't foresee any compatibility issues.
3. This is an expert-level hack. I don't know if we ever got around to creating an IPS of this. You may have to read through the forums and compile the ASM/make hex edits. I want to say that i got 95% of the way to finishing this, but the last 5% conflicted with Divergent Paths, so I never went back and created a standalone.
4. Yes, it's compatible with almost everything. It touches parts of the code that aren't normally updated.
5. Version 1.0
