@mitu I was just messing around with all of this. I don't have a RP4 yet, but plan to get one. I just wanted to get familiar with the different gaming-centric OSes before I got mine. I'm running this on a laptop that's running Windows 10. I need the ability to have Windows 10 running while I play around with this RP and emu stuff for the time-being. Using VirtualBox gives me that ability. I checked the '3D Acceleration' checkbox and now RetroPie runs. However it's really slow and beyond the configuration menu, I don't see anything else. I've got a VM that only loads an SD card (no 'host' VM OS) of another gaming front-end and the speed of it is great. I'm guessing the slowness has to do with running a system in a system in a VM (or something like that). That's cool. I just wanted to see it.

@Clyde said in Storing ROMs and other data on a remote drive:

You can set it in the file /home/pi/.emulationstation/es_settings.cfg via the line <bool name="ParseGamelistOnly" value="true" />.

Finally got around to try that out. I didn't notice any real difference in starting time. It spends 80%-ish of the EmulationStation load screen with "Loading system config". The total time from console to be in the UI is ~1 minute regardless if ParseGamelistOnly is set to true or false.

It might be my setup, because there's no es_settings.cfg file available so I had to create it myself:

<?xml version="1.0"?> <bool name="ParseGamelistOnly" value="true" />

That kind gets me thinking, someone needs to write a Raspberry Pi emulator now. :-D

It already exists, but emulating a video card is not included, so there's little use for RetroPie experimentation.
There's nothing stopping you from using RetroPie in an x86 PC (virtual or not), it's the same software that's installed on both the PC and the Pi, it's only the platform specific configuration and hardware capabilities that are different.
But if you intend to use a Pi, just get one and start experimenting. It's not a big investment (ok, it might be for some) and you already have the controllers and the TV/Monitor.
