So far the DragonBalls currently do not work in any of the maps. The radar is easy, you just push F9 I believe and it will bring up a scouter which you can cycle between modes. The senzu beans are a pain to find, I only know where they are on the riverside map, not to sure about the others.
None of the maps work with DragonBalls, Riverside does not work due to none of the DragonBalls being above ground. Besides, you do not have to get EVM just to get the DragonBalls, just look on ESF-World to find custom made maps that have them.
