So you downloaded Haxchi.... Well done, you completed step one.
Have you installed it to your console using one of the compatible PAID for nds titles?
If not, I would recommend you look at the below thread first

First of all, you should first acquire a little "knowledge" about the whole matter. Just downloading stuff and hoping that it "somehow" works will not help anyone. If you would use a reasonable guide, you would already know what to do with haxchi. Read the steps carefully, do what the site says, and have fun afterwards.I just have downloaded Haxchi . Now what?
