The main problem here is that when EMSCRIPTEN is defined the Player switching to a different execution mode: It tries to download a directory index file from the web and afterwarfs fetches all assets on demand (when they are used for the first time). This makes the startup much faster but probably not applicable for libretro.

I assume libretro puts the whole game in the virtual filesystem, so it can use the normal directory reading code as on the desktop?

@twinaphex would likely know more than me.

Removed from emscripten build over at libretro/libretro-super@2a09b86 for now.
