Identify additional cores to include out-of-the-box

What are the compatible licenses that can be included?

That's a good question, and a difficult one. A while back I did some digging and found this: https://www.gnu.org/licenses/gpl-faq.html#AllCompatibility

So it seems like with the app being under GPLv3 that:

• GPLv2 content would not be compatible
• GPLv2+ content would be compatible
• GPLv3 content would be compatible
• LGPLv2.1+ content would be compatible

From https://www.gnu.org/licenses/license-list.en.html:

• MIT appears to be a bit of a misnomer, and instances of the text that I’ve read seem pretty clear that it can be compatible. The above site states that it’s compatible with GPL, so GPLv3 shouldn’t be an issue.
• MPLv2 content can be used and compatible under GLPv3 so long as it is not modified. If the MPL content were modified, the resultant product would have to be dual-licensed.

I think that covers most of the cases I've seen for Libretro cores.
