Naruto Ultimate Ninja Heroes 3 black screen issue

[D3shly]

Greetings, I've recently found out about your application, PPSSPP. I immediately liked the idea since it will help me play games on my smartphone that can bring back many memories from my childhood. I then downloaded "Naruto Ultimate Ninja Heroes 3", and I was so excited to play it. When I opened it, it gave me the intros that usually come up and should come up, so I thought it was working and all. However, after these intros, a black screen followed and then the game didn't do anything for a lot of time. I was stuck on a black screen. I could tap and move the joystick and the other buttons on screen, but the main content was just pure black. I have been trying to look up this problem for almost 2 weeks now, and every video I see, the fix they provide is a fix that is not compatible with iOS, like for example File Management(Android/PC) and Command Prompt(PC). I need help with fixing this problem on my iOS device, running iOS 11. The PPSSPP version I have is PPSSPP v1.5.4-336-ga989b4a93. Thank you, have a good day.
