I'm having trouble finding the last remaining dragonball. Now i know there are several topics about dragon balls on this board but none of them specifically answer my question. So i know that some dragonballs can be found in areas where this is no scouter/dragon radar to help you out, but i checked all over and i cannot find the last dragonball.
Anyone know of a place i might be missing. I know i did the dodoria stage, frieza stage and the buu stage. Any other places i should check?
Check my post by typing in the search field "all dragon balls". It may help.
There is one dragon ball every single free roam scene (even if it does not initially show up on radar or by searching, you have to defeat a series of battles to reveal it).
You haven't listed the double android scene, so I suggest that one. It's the one with Android 16 crusing around with Android 17.
Also try Trunks, and Teen Gohan. The battles I fought to unlock the hidden dragon balls are also listed in that post (I don't know if they'll be the same for you). Fight the battles and then cruise around using the R1 bumber (for search). If you've unlocked the hidden ball then it will show up on the search even if it does not show up on radar.
