Hi MikamiFan92,
The issue you're describing is a known issue with Duckstation. It's caused by a bug in the emulator's implementation of the text rendering engine. The bug causes the emulator to render each character in the textbox twice, which can significantly slow down the game.
There are a few things you can try to fix this issue:
Use a different emulator. There are a few other emulators that can run Dragon Warrior VII, such as ePSXe and RetroArch. These emulators don't have the same bug as Duckstation, so they may not cause the same slowdown.
Disable text scaling. In Duckstation, you can disable text scaling by going to the Settings menu and unchecking the Enable Text Scaling option. This will make the text smaller, but it will also reduce the amount of work the emulator has to do to render it.
