Can't get Adhoc?

[shadowraid5]

So i've been looking at the forums for doing multiplayer with ppsspp with a friend of mine, all of the tutorials say to get adhoc and have a dropbox link but all those links come up as the file being moved or deleted.

Is there anyone that can still get adhoc? Is there somewhere i can find it to download it? Or is adhoc not allowed anymore and multiplayer is now impossible for ppsspp?

Please help
