Filter vertical games MAME

[RoughDuck]

Hi searching the internet I discovered a helpful guide(https://github.com/mickelson/attract/wiki/Example-filters#Vertical_SHMUPs) for filters where he uses this rule:

rule                 Rotation equals 90|270

Where is rotation defined?  If I use this with my xml/catver/player.ini it doesn't work because as far as I can tell no where is there a tag that says "Rotation".

EDIT: Nevermind I reloaded Attract Mode and it seems to be working now.  Maybe a conflict prior was causing issues.

@RoughDuck
after generating your mame-romlist > check the romlist

in my case:
C:\attract\romlists\mame.txt

#Name;Title;Emulator;CloneOf;Year;Manufacturer;Category;Players;Rotation;Control;Status;DisplayCount;DisplayType;AltRomname;AltTitle;Extra;Buttons
