you might be able to with wii games. I'm not sure. I think they only use the product code, which is how loadiine identifies that there's a game in that folder. wiiu uses product code followed by iirc the first two of the company code. if it needs a company code, just put 01, which I think is Nintendo. I'm not sure if it will use the product code of rhythm heaven or not. you can check in the meta.xml. that's where the company and product codes as well as game name or what's displayed on the home menu are located.
