I'm confused as to what to do exactly I have Homebrew on my 3ds device but you keep saying dump the rom dump the rom and I'm confused because I'm trying to use a cartridge for the hack so I'm not sure how I can dump the rom of an actual 3ds cartridge on my computer so please help me.

So I currently am having trouble working to get this game to work but I sadly have no clue what i'm doing as i'm new to this rom patching and hacks for Fire Emblem please if anyone can help me that'd be amazing!
