Ok
In cycle means that it is displayed as a sub menu, if it was no then it would not show
If you have in menu yes, then it would show on the main menu, which you do not want, and you need to select no so it becomes a sub menu
The @ is saying that it is a sub menu, it is replacing where normally the emulator name would be.
The 1 & 2 is where the year should be so 2022 as an example
However, I have replaced the 2022 with 1,2,3 etc so if I want to sort on year rather than title then it uses that. You can still use years so Sega Master System 1986 Sega Mega Drive 1988 if you want to check the year date, but for me I want some menus just to display in order of how I want them, I could do 1970,1971 example, but it is far quicker just to type 1,2,3
Another example for you, this is part of my collections
Bubble Bobble All Games, Bubble Bobble Arcade, Bubble Bobble Computers, Bubble Bobble Consoles, Bubble Bobble Bonus Games.
If I had it sorted on title, the bonus games would be after all games, but I do not want that, I want that selection at the end. So I have All Games = 1 Arcade = 2 Computers = 3 Consoles 4 Bonus Games = 5, I then sort on year so that it displays in that order. As said before, I could type in 1986, 1987, 1988 but it is much faster to type 1,2,3. However, it all works the same way.
As for how AM is programmed that is not down to me, but this is how you need to do it for sub menus
Just for more info, I have broken down the fields into colours the @ is in green which is in the emulator field, but we are replacing the emulator with @ to create a sub menu, otherwise that field would have MAME, RPSC3 etc in that location
#Name;Title;Emulator;CloneOf;Year;Manufacturer;Category;Players;Rotation;Control;Status;DisplayCount;DisplayType;AltRomname;AltTitle;Extra;Buttons;Series;Language;Region;Rating
Sega Consoles;Sega Consoles;@;;1984;;;;;;;;;;;COIN OPERATED CABINET;;;;;
If you look at the below line, it tells you the way that it populates the fields, so the ; is a separator so Name;Title;Emulator; WE ARE NOT BOTHERED ABOUT CLONEOF OR OTHER INFORMATION (apart from year) BUT WE STILL NEED THE ; TO BE IN PLACE. SO AS AN EXAMPLE IF YOU WANT TO ADD THE REGION AT A LATER DATE, YOU NEED TO COUNT THE ; 19TH AND THEN PUT EUROPE INTO THAT SPACE
1st 19TH
#Name;Title;Emulator;CloneOf;Year;Manufacturer;Category;Players;Rotation;Control;Status;DisplayCount;DisplayType;AltRomname;AltTitle;Extra;Buttons;Series;Language;Region;Rating
; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; Europe ;
