Now running 1.5.0 and I see that box art for any and all games that have an ampersand (&) in the title do not show the box art PNG files at all. The Adventures Of Batman & Robin, for example. Is there a naming scheme for the PNG files or is this a bug that will be fixed? A while back it was fine. Thanks!

I noticed this doesn’t happen in the 32-bit version but happens in the 64-bit.
In my computer, I manually renamed the .png files and game titles on the playlists, changing every “&” to “and”, so the box arts would show again.
Use “_” (underscore, without quotes) in place of any character not recognized correctly in your art files.
It works! Thanks!

Thanks for the information about replacing the ampersand (&) with an underscore (_). This worked!
