ok, i originally posted this over at the emulation station repo, but since the development is on a kinda hiatus, i thought i'd post here, to see if theres any help etc,

i've been trying for some time to get gamlists.xml to show/work in sub folders, with the aim to reduce the number of emulator menus on the main selection pages, so i can have a snes main folder then that containing the sub folders of eu/usa, japanese, translations, hacks and so on this will for me drastically reduce the sizes of my game lists and i'm hoping the will be a little bit more responsive too

edit: if this is already a feature.... could someone please give instructions

thank you

It might reduce the size of individual gamelist.xml files, but it will not matter for responsiveness, as all systems are read/parsed upon startup.

Unsure if related or helpful, but worth noting that while you cannot split the gamelist for the different sub folders, your gamelist files can reference files in sub folders, hence allowing you to organize your ROMs in the way you described - though they are stored in a single file, on the system's root path.
