I think you have to DLDI patch it (just a guess). I'll try to explain this the easiest I can.
Download "DLDIrc" from here. You'll find it at the bottom. Now when you install it, select DS-X for your patch. Now when that's all finished, all you have to do is right click the styxds-dldi-v01a.nds file and select "DLDI patch with DS-x" or something to that effect. Then follow the command prompt.
Hope that all helps.
