@mitu

Okay I understand now, thank you mitu 👍🏻.

@Arctic452910 In general this would be more a "Pokemon" related question and not a retropie one (trading Pokemons). For emulator specific questions I suggest you to provide all the info requested here and to take a look into the DOCs for those, as the availability to "Link" the emulated system(s) may be limited or not available at all.

@sleve_mcdichael said in Going from Pi 3 to Pi 4 and keeping all settings, high scores, and so on:

Yeah, probably the controller profile was in this "configs" folder, which didn't get copied over with the other three.

I did that - synced the config directory. I've run into a problem and, since I felt it really wasn't a part of this topic, I started another thread on it. In short, all the controls on my arcade cabinet work except the spinner. I'm hoping there isn't some timing issue or something with the Pi4 that doesn't get along with the spinner.

@sleve_mcdichael said in Going from Pi 3 to Pi 4 and keeping all settings, high scores, and so on:

Aye, then yeah will have to copy them over the new system.

One thing I just love about Pis is that you can do that. You can pull a card or USB stick out of one and plug it into the other and it'll work fine - or you can pull the "drive" out of one and easily plug it in another and copy all the data to the new system.

@mitu Problem solved. As I suspected, it was something stupid that I was doing that simply wasn't making its way across in communication.

I thought pressing [F4] just quit the controller config and would take me to ES. I didn't realize it was that which was kicking me to the CLI. facepalm

Everything is good now. Thanks for your willingness to help.

@berlinhimmel Unfortunately not, quite a lot of games on consoles have different memory processes for the NTSC and PAL versions, so the saves aren't swappable.

@sleve_mcdichael Thank you, I'll begin to try this once I setup my Pi

@tango Thanks for this comprehensive writeup. That's the spirit of a community. :)

For all coming accross this post: This guide works only for Rpi 3B+ (Note the +).

For other models suppporting USB mass storage boot see prerequites here: https://www.raspberrypi.org/documentation/hardware/raspberrypi/bootmodes/msd.md

@sibsonian said in Migrating a build from RPi3 to Rpi4?:

I know the configs dir will migrate the artwork and ES settings. Common sense would lead me to believe that I would also need to reinstall any optional packages and themes, yes?

Correct.
You will need to install the optional packages that don't come standard on the image.

You're right, I've edited my post accordingly.

@Parabolaralus
Yeah I'll either figure it out or install linux (what is a good distro for dell laptops?). This pc I found at a garbage dump, the hard drive was failing, the battery shot, and it was a little beaten up from being discarded. I restored it with a ssd, and a new battery.
I think it came with windows 7, but there was no sticker on the back.

I downloaded the USB Windows 10 upgrade from microsoft, these were free upgrades some time ago. I had assumed Education postulating that it would activate for free, but I have no qualifications for those terms.

Back on topic:
ExFat has been working great with allocation unit size 8192b.
NTFS-3g may have been a problem in particular with dosbox because of the write syncs.

@mitu
The device setup I was thinking would be like this on the raspberry pi
USB1: Usb image boot, raspbian? smaller.
Micro-SDslot: unformatted new microsd (the target of the image write)
USB2: Usb microsd adapter (the source of the image write)

rpi-clone; and I thought I made it sound confusing.

@Krytern
That's a good question. The configuration exists. I read that the sd_overclock has to be a multiple of the core_freq, otherwise it will choose the next highest factor.

@taiJones00
So does the wireless work on the game girl? It would be cool to write a script to easily disable and enable it to save power.

Is the hdmi port still accessible? and then you might be able to sync a wireless controller and play on a tv.

The RPI3b+ can get hotter than any of the other models, I wonder if installing a fan would be possible. Of course that would use more power, depending on the emulations you want to use, it would be easy to down_clock the cpu and benefit as well.

@ByteThis I thought about hooking up a lan cable but i’m too lazy to run one from my router behind my furniture and to the pie.

I used the automatic way of doing it by just making the retropie-mount folder in the root of the drive and plugging it in to the pi and just let it do its thing.

Thanks.

All i did on my retropie was enabled ssh and 1 wire turned on network discovery on my pc and it worked! With a cat 6 ethernet cable

@clyde That's it! The KISS principle. I like that one.

@sub_atomic I hope we did not "scare you away" from setting up a remote connection. Just take your time, read up on how to do it properly and you'll be fine.

But doing it together with your nephew is a thing that I can 100% second. Passing on the love for and knowledge of tinkering and a little coding and IT stuff is always something good. :)

Cheers!

@mediamogul Wonderful.

You need to copy the ROM folders contents to your PC or a USB stick, then transfer them over to the new image as you did initially. You might have to write your backup image back to the card in order to copy the ROMs.
