I'm not sure if it's a problem with the emulator or the rom, but even though I did game to work, and the frame speed isn't so bad, it's...pretty much unreadable, as the dialogue box gets randomly cut off. (Screen is here 847d534d90c57a71c913f6e4ad7489a6.png ) Does any of you have an idea how to fix this, or if it's even possible?
