Problems with almost unreadable text in Banjo Tooie in Emudeck

I just installed Emudeck today and launched Banjo Tooie in Retroarch. It played great. But after I closed the game and started it back up I noticed that the text had become almost unreadable. I thought that maybe I messed up by changing the in-game display settings and I fiddled with some settings in Retroarch as well. I deleted the retroarch.cfg file to reset the settings in case I messed something up in there and I also tried launching the game without my current save file and that somehow worked the first time, but after closing the game and starting it back up I encountered the same problem. Anybody know how to fix this?

Edit: turns out the rom was probably corrupted. Thanks for the help!
