Alright. Perhaps you could add the patch information to the wiki as well?

It would be really neat if we could incorporate this stuff into the wiki somehow. We should work out a simple format on how it should be done so we can do the same to the other patches as well.

I just edit the text to keep the same terms which were in the page.
How much deep do you want to go in technical details there?

The point of tracking stuff like that is more to make sure that patches don't clash with each other, so I'd probably, I think, make a page of the entire ROM map _and_ then make notations at each address that's been modified what the patches (so and so) did.

Like:

THIS IS THE ROM MAP page.

At certain points, make a link at certain addresses to the patch that modifies this or that.

Make note that this patch will clash with -that- patch if you use it. (I.E. the Legend of the Spooniest overwrites this... the ICON patch overwrites -that-...)

Another reason to do this is so people can re-create patches from the documentation. How about we do something like this?
http://slickproductions.org/slickwiki/index.php/FF5_Patch:Un-Berserker

I figured it would be nice to know the original value of the bytes so it's easy to undo the patch if that is desired.

That's a good idea! You can take care of that if you feel like it. To create a new page, type the name of the page into the search field and click search. Then click the option to create a new page.

Ok. Once I finish up with the Legends of the Crystals update, gonna jump back and poke at IPS modifications.

https://www.codeisle.com/products/international-patching-system-ips-patch-viewer/

That seems like a decent way to get a quick list of bytes changed, yes?
