Because of the way LB does its adds and appends characters and what not as well as handles special characters, this is tough to handle. The primary issue comes if you add them yourself and it detects them. If you scrape, it will work much better. There is no way for me to tap in to what file LB actually thinks is associated with each ROM exactly. I have to make lots of assumptions. Because I scrape and update, mine is almost 100% accurate.
