Main Menu Wheel doesn't show up

[NEO207]

Hi there, I got a problem. I have a wheel for WonderswanColor in my Main Menu. The Wheel doesn't show up, until I enter any wheel (while the missing wheel is on-screen) and go back to the main menu.

You can have a look at the attached photos.

I already deleted the png file and replaced it with a new one from google. Still same issue.

Does anyone know how to fix this problem?

That usually means your system name in HS and the image name of the wheel differ in capitalization, they need to match. So if one is "WonderSwan" and the other is "Wonderswan" it will appear randomly.

you are a genius! Thanks! Database used WonderSwan, the Theme, PNG File etc. used Wonderswan.

Now it works. I am really happy about that how quickly you guys can help me and each other here.

keep up the good work!
