FE8 Custom Animation Help

[Yetiplays]

Okay, so, I've been hacking for a pretty long time, but I've only done minor stuff (to fire emblem atleast) and I've found a lot of amazing custom animations I'd like to try adding to my game, and while I've read the tutorials and understand how, my current problem is that I want to start with a pre-hacked base rom, specifically: http://serenesforest.net/forums/index.php?showtopic=58795 why, because this hack fixes every problem I had with fire emblem 8. What I'd like to do is add some custom animations to add some new weapons to specific classes to make the game a bit more challenging.(I'd be giving the enemy these new weapons also)

My problem is however that I tried opening the rom in Feditor and it wouldnt let me access the animations at all, but I opened a clean rom of FE8, and it did allow me.

So my main question is: is there a way for me to add the animations to this hack, or is there no way for me to do so.

If you need more information I'm happy to provide it.
