Sub wheel catagory further in mame wheel

[Gothicplsur]

Hey gang! Long time viewer, sort of new poster.

Here's my question: I am current with Mame .209 100%, which includes everything, Mahjong, Casino, Quiz etc. Can I make a sub wheel to list "Mahjong" or "casino" and have those show up just in that sub/sub wheel instead of seeing them list in the Mame games wheel? Kind of like a genre I guess to a point, but as you're scrolling through the Mame games, you come across "casino" push the button and it goes to all the Player's choice or slot machines etc. Same with "quiz, Mahjong", this way I don't have to delete them from the XML so they don't show up. How would I go about doing so in creating a sub/sub wheel? Thanks for any help in advance

I think what you're looking for is nested wheels... start searching for that in this forum and you'll see a couple of options. It's not something native, though, so it's a little tricky to implement. I find it far easier just to split things out into different main wheels, but that's just me.

Good luck!

That's Griffin, I kinda thought maybe that would be the route I might have to take it would be easier for sure, I'm just thinking too, when a new version of mame comes out how easy it would be or not to separate new roms to the system. I'll search for what you described. Thanks Again!
