SD Gundam Over World bugs

[Sdust]

I used version 1.6 and now using version 1.8 for playing SD gundam over world. It has several bugs.
1. If I used support attack of ship, PPSSPP will exit and show a error window.
2. Can't get in all options in main menu. For example when I click story select button, all options will leave and only a background there. Then all operators are useless.
3.Amuro's face not shows when he taking. Instead of his face there's a "..."

Anyone have tried this game in 1.8?
