After serveral days looking for a solution, I have to say that it was impossible for me to do that.
How can I add a submenu of the displays menu?
This plugin seems the easiest method, but the link is broken.
I would like to add some submenus based on filters , something like that:
Main menu: displays
Sub menus: Platform/puzzle/.. (filters)
Final menu: Games
I thought it had to be easy... please some help!
The way I have done it is:
1- Platform Menu/ Display: Platforms like arcades/ computers/ consoles etc
2- Systems menu: In consoles Sega saturn/ dreamcast/ nintendo 64 etc
3- System menu: Games organized on Genre Filters like action/ adventure/ horror etc
Now above mentioned organization scheme is easily achievable without much tweaking as everything you need is already available in AM. I've described the process in detail here>

The organization scheme you are trying for can work easily without platform menu because you are looking for Systems> System (Filter: Genre)> Games (as opposed to Platforms> Systems> System (Filter: Genre)> Games). That is what I understood from your post but if you mean you need a unified or mega list of genres like a action/ adventure encompassing every system then you will need to develop new romlists (this too is easily achievable from with AM.
For organizing games in genre, I am using the following in attract.cfg
display Microsoft MSX (blueMSX-Retroarch)
layout RetroMode
romlist Microsoft MSX (blueMSX-Retroarch)
in_cycle yes
in_menu no
filter ALL
sort_by Title
filter ACTION
sort_by Title
rule Category equals Action
filter ADVENTURE
sort_by Title
rule Category equals Adventure
filter "BEAT 'EM UP"
sort_by Title
rule Category equals Beat 'Em Up
filter FIGHTING
sort_by Title
rule Category equals Fighting
filter HORROR
sort_by Title
rule Category equals Horror
filter PLATFORM
sort_by Title
rule Category equals Platform
filter PUZZLE
sort_by Title
rule Category equals Puzzle
filter RACING
sort_by Title
rule Category equals Racing
filter RPG
sort_by Title
rule Category equals RPG
filter SHOOTER
sort_by Title
rule Category equals Shooter
filter SPORTS
sort_by Title
rule Category equals Sports
filter STRATEGY
sort_by Title
rule Category equals Strategy
Just make sure:
1- Controller mapping allows from moving from one genre to next
2- Genres are properly listed in romlist. This might warrant manually making the changes, as you want uniformity across the lists.
