Could you please test a different game with this on ios 9? im on ios 9.1, and i tried two other games so far, and the hacks didn't even affect them (as in, no crashes, no new cheats, no anything). I followed the process in the exact same way i did for rover craft, and i transferred all the files in the correct folders. i tried the hacks for "drive ahead" and for S.O.L. (stone of life).
I used to have jailbreak but then cydia somehow managed to destroy my ipad and i had to restore my ipad completely anew, and i didn't have any backups of my data (new laptop). So until the jailbreak for 9.1 comes out, ill be appreciating all the help us ios 9 users are getting from you .
