Info file has tons of extensions

I hardly even want to bug you with an issue for this, since I think I know the answer already, but I couldn't find anyone else asking about it and maybe it'll be helpful to somebody in the future.

The info file for the scummvm core has an enormous number of filetypes in the supported_extensions directive, including things like .C, .IMG, .TXT, .MP3, .CFG, and .TTF. The effect is that if scummvm is installed, then an awful lot of odd files will pass the "Filter unknown extensions" check and show up in Load Content, cluttering things up if your disk is a mess. Am I right in assuming this is necessary and unavoidable?

Obviously it's not a cause celebre; virtually everyone (except me) is using well-maintained ROM folders and will never even know this is happening. And I assume it's necessary because ScummVM has to access the raw files of many different games straight from the disk, and if it doesn't specify all this stuff in the info file, then the file access APIs will refuse to expose any of those files to the core. And this is probably unfixable without extending the APIs with a "no_seriously_show_me_everything" flag, which isn't worth the impact since virtually nothing else will ever need this functionality.

If that's all correct then go ahead and close, ty! 👍

Hi, all the extensions shown in the core info file are absolutely not needed for the core itself, it would work perfectly even with no extension indicated at all (though I would indicate just the .scummvm).
Those extensions are only needed to let the external ScummVM.dat from libretro-database work to generate a ScummVM retroarch playlist from the frontend.

Actually this is not the right way to generate a ScummVM retroarch playlist (info about how to do this properly are shown in the help section of the internal ScummVM Launcher, soon or later I will update libretro docs as well) and the ScummVM.dat is not handled by me or the ScummVM team.
Anyways I don't like to break this legacy feature unilaterally core-side, I will do if ScummVM.dat is dropped from libretro-database or if it becomes evidently obsolete or abandoned.
I will leave the issue opened as an enhancement, pending on ScummVM.dat removal, to be re-evaluated in the future.

To solve your issue locally, you may open your scummvm_libretro.info in the core info folder and remove all unneeded extensions, though the file would be overwritten during next update.
