Is there any way to always summon porunga with the dragon balls? I collected all 7, went to a stage in namek with the time machine, summoned and got shenron. I was thinking maybe the last ball collected needed to be from namek? Anyone know the answer to this?


I should probably add I've done three summonings, the first was shenron, then porunga, then shenron again(even though I was on namek)

Thanks
