ROM Hack OR/AS romfs 'a' folder content notes

[Coleman_C18]

First I will start off by saying that I did not make these notes or have any thing to do with the process, I am merely transferring them from Kaphotic's pastebin into this post for a wider audience. With braindump and hax 2.5 out romhacking has a wider reach, it is important to share this with as many people as possible!
The original source is free to view on pastebin http://pastebin.com/u/Kaphotics.

If anyone has any notes to add to the list please leave a comment and I will add them in!
