For those who are crashing I found a fix
On the 2.8.1/2 Japan hack I turned on cleared out the numbers it was blank then I turned the hack off.
I then deleted the hack then I downloaded an old version of the hack 2.4.1 then I resprung. I turned it on went to the app nothing happened. I went back turned off then deleted the 2.4.1 hack then I decided to download the 2.8.1/2 hack and I put the value as 0 (on all of them) then I went to app, it didn't crash so I decided to close app and put 100.0 on hack went to app and it worked! So I decided to use my best value 10000000.0 went to hack then it worked no crashes nothing. If it does crash try opening the game again. If it's still doesn't work try doing a respring on a few of the steps.
(Btw I downloaded the old hack in Cydia just search Dragon ball and it should appear 2.1.0 hack Japan my bad not 2.4.1 and if you're not finding it add this source http://airmax.yourepo.com/ )
