Since modern #RetroGamingHandhelds are essentially small #Linux machines, I can set #Mednafen to take screenshots and put them in a folder that gets synced to a big PC. Neat!
Specifically, with #ROCKNIX on #RGCubeXX, I changed mednafen.cfg:
```
command.take_snapshot joystick 0x4ed02f893c2a5ffb0004001100000000 button_10 && joystick 0x4ed02f893c2a5ffb0004001100000000 button_1
filesys.path_snap /storage/roms/screenshots/
```
button_10 + button_1 = M + A, same as with Duckstation.
