How to get to Sacred Grounds/ Hell in 3DS?

I'm sorry I'm asking so many questions..

What I've done
*Saved Curly
*Drained Water from Curly
*Restored her Memory
*Defeated Undead core

when I try and open the house/building while the earth-quake Is happening, It says "The Door won't open!"

Help? :c


..I know theres topics saying how you access hell, but as far as I can tell, I've done all of the requirements.

 

You need to talk to Curly in the plantation and get an item called the Iron Bond from her

 

Well now I'm pissed.
That took a while to finish (For some reason, more than the PC Ver.)

I forgot the Iron bond.

Damnit.

 

yeah you need to do that and get booster 2.0 if not then oh well. and i recommend getting the spur

 

I did get the booster 2.0, Obviously. and I got the spur too.

I'm not new to cave story.
