Add snaps to default install methods

[eje211]

I had to install Dolphin on my own. RetroPie wanted to compile it on my machine and that didn't work. I installed it using a snap. I fooled RetroPie by adding two placeholder files, dolphin-emu and dolphin-emu-nogui in the build folder. Then, I changed the emulators.cfg file as per these instructions.

The way I did this is extremely hacky. Now that I moved RetroPie from a Raspberry Pi to an x86_64 machine, I also wanted to install PCSX2. It seems to have worked. PCSX2 also has a snap. I tried on Ubuntu on another machine and that worked extremely well. Currently, I've only seen two installation options on Linux: "from binaries" and "from source."

I'm wondering if installing from snaps might not be a great option for x86 machines. Yes, they would exist outside of the RetroPie environment, but on the other hand, they tend to be extremely reliable.

Where are the scripts that configure that? I tried looking for them by grepping, and the closest I found was a function in scriptmodules/admin/setup.sh.

First of all, is this a good or a bad idea? Also,

Where could I find the sources to get started?

Thanks!
