Harvest Moon: Hero of Leaf Valley

[Danieller]

Sorry, I'm trying to search ideas all over the internet and i haven't found any. So I downloaded harvest moon hero of moon valley.iso with ppsspp gold. I also had cheats installed. I'm just too bored and tired of the hardworkimg part of making money. So, my problem is.. Everytime I go to the mining cave, and try to do part time job (first time), and I run towards the blue stone, my game first, lagged. Now it crashes. I tries replaying it several times. I tried the best settings for it and it didn't really help. I really hope someone knows something about this here. Thanks!
