Princess Maker 5

[mycot]

First off, I would like to thank the people who've made this incredibly useful and intuitive program. I have used it many times.

Unfortunately, the reason why I am posting is because I've run into my first error trying to play a game (the Korean version of Princess Maker 5). The screen looks like the attached pictures, with the screen looking like it's repeating and overlapping 3 times (ignore the Walter White desktop picture).
The game actually runs normally (I can press the buttons to advance), but obviously is not playable.
I've fiddled with the graphics settings but have not been able to fix it. I've also tried multiple ISO files. so it's probably not corruption. And again, this is not the first time I've used ppsspp on this computer, so it's not something relating to that either.

I would greatly thank anyone who could suggest what I'm missing or identify the problem; the game is so obscure I can't find any similar cases.

edit: for completion's sake I'm going to fill out the normal OP form.
