cannot use libretro core without manually downloading assets

[soredake]

see https://github.com/libretro/docs/blob/master/docs/library/ppsspp.md#bios

What happens?

Assets not copied automatically.

What should happen?

Assets should be downloaded with core.

What hardware, operating system, and PPSSPP version? On desktop, GPU matters for graphical issues.

No idea how to solve this other than baking the assets into the binary. Not sure what other libretro cores do?

I feel like this is a widespread issue of libretro, and less an issue of PPSSPP itself?

Yeah, I don't know that there's anything sensible we can do about this.

@hrydgard When the LibRetro team started porting PCSX2, they said this:

Reducing file requirements

As a general baseline, Libretro strives to make sure that the cores we self-maintain are fairly portable. We’d like not to have the user to require to install several data files inside the System folder in order for an emulator core to work. The problem with the PCSX2 core up to this point was that it was too much of a straight port – PCSX2 by itself writes to dozens of files during startup and logging. However, it also has many config files scattered about the place.

We have cut all this config file reading/writing. Now, the only configuration file that gets written to is the ever-trusty ‘core options config file’ from Libretro/RetroArch.

Furthermore, the only files you need to have in your /pcsx2 folder are your BIOS files inside /pcsx2/bios. Anything else is not necessary.

So, I believe that all their assets (e.g. cheats, databases) end up embed inside the core itself, or did i get it wrong? I'm not a developer nor do I know if it's possible to do the same with PPSSPP, but browsing through this issue I decided to leave this my 2 cents contribution.
