Animate Wall effects

[purplepixie]

So, I'm hoping to make Warmonger's Chariot and I can't get it to work ...

The only two living examples I can find of the effect are the original Animate Wall and Rolling Stones.
Neither of which have code, I assume Rolling Stones was done in assembly, sadly enough for me.

So, I thought I'd have pretty serious hack and create a pointer to animate wall's code pointer and just call the card, after setting instance->targets[0] to the equipped creature.
But nothing happens.
Do the old, built-in cards use instance->targets[0] for their "who am I enchanting" tests or do I have to do something else before calling animate wall?
Or, alternatively, is there a better way to do this?
Like I've said before, I really don't know a whole deal about assembly and I rather doubt my ability to do this outside of C

Or am I just missing something else - I made sure to return the value animate_wall returned if it did, and I copied the whole reserved info out of it and still nothing.

Thanks,
Pixie
