Someone has asked me to make a intro for a ROM (dunno if it is good or bad, I just stick to the point).
However, I don't know how to make one! They ask for a IPS of the intro so that the ROM can be unpatched later, also I don't know how to make one of those!
Could someone tell me how to make a intro?

What do they exactly mean by intro? For my games' 'intros' I just have a bitmap of my company's logo fade in and then out to the title screen...

To patch an intro into a game, I think (I've never done this) you change that first branch instruction to go to the very end of all the code into your new code. Then that plays the intro - and when the intro is over, you branch back to where the original branch said to go. E.g.:
Original code:
branch HERE
Nintendo logo, header info, etc...
HERE:
normal code
Patched code:
branch INTRO
Nintento logo, header info, etc...
HERE:
normal code
INTRO:
your code
branch HERE
Make sense?

Sure it makes sense, thanks!
How do I make a IPS file for it then, if I don't have the ROM?

I don't think there are tools for making IPS files if you don't have the original file. As the IPS file format work with only saving the differences between the 2 files. You could probably make a program that makes IPS files with only a "filler" that takes some data and places it at a specified address.
