I just bought this game from Play Store, backed up the APK and obb, then refunded it. The first time I run it i get "authentication failed". But if I turn on license verification emulation in
Lucky Patcher , game starts fine.
It's weird, because I have a cracked/modded Play Store installed, which is supposed to verify licenses for all apps even if they're pirated. But for some apps, it seems to be hit or miss. Sometimes game starts fine, sometimes not. I just toggle the license switch in LP, that fixes it for awhile.
I did the same thing as above with Romancing Saga 3, same results. My device is rooted, in case anyone is wondering.
I'm really enjoying both of these games alot, brings back memories.
