[Feature] Handle Switch "Update" and "DLC" files

[Djiit]

Is your feature request related to a problem? Please describe.
My Switch roms folder contain both main titles and updates (NSPs).

Describe the solution you'd like
When scanning a swich platform folder, I would expect romm to ignore updates titles (not main games) -- or flag them as such.
is it possible when fetching data from titleDB to flag some files as "updates" or "DLC" only ?

Describe alternatives you've considered
Renaming my updates using a pattern (e.g. update.nsp) and ignoring them via the configuration.

[Djiit]

was looking at #404
it seems my game+updates+dlc were not found as being part of the same group. Do you expect the naming differences to be all between parenthesis or square brackets?

edit: adding a space between the title id and the rest of the file name worked.. e.g. Hammerwatch v65536[01003B9007E86800].nsp => Hammerwatch v65536 [01003B9007E86800].nsp.

Should we document such constraint somewhere ?

this is not something romm does at the moment, and i don't know enough about titleDB to know (off the top of my head) if that's possible. i also don't own a switch so i'm not aware of the file structure.

we don't currently support that strutcture, you'll need to wait until we build sync-with-device to support other folder structures

adding a space between the title id and the rest of the file name worked

that might be a bug with the regex that parses titleID, we'll have a look

Thanks for the quick and detailed answer.

If you can point me to the corresponding regexp and associated test, I could have a look at it.

Here's the entry for Hammerwatch, you'll notice the key is 70010000003234 and the id is 01003B9007E86000, which differs from your filename. That being said we don't use the id field to lookup games, just the key. The relevant code is in igdb_handler.py if you wanna have a look.

Indeed, the "update" id differs a bit from the game id. FWIW, according to https://switchbrew.org/w/index.php?title=Title_list/Games&mobileaction=toggle_view_desktop :

Note: Game updates have the same ProgramId as the main application, except with bitmask 0x800 set.

Could we use this to group titles together?

I think so yes! Let me see what I can whip up really quick...
