Basically, in some battles the app crashes. It just pushes me back to the main menu

If I create a savestate a few seconds before a crash happens, then the crash is going to be exactly the same.
It is weird, but I'd have found a solution. In the beginning, if I put the frameskip value in 7, 8 or 9 and begin from a savestate seconds before a crash, then it all was perfect, but now even if I do that, a lot of crashes persist. Maybe, I think a crash occurs when de cpu-speed is lowest, because activating the frameskip makes the cpu-speed faster (I have a Motorola Moto G, it is possible this device is not suffice to run Drastic and some games, I think).
I'm sorry for my english, I'm mexican.
