Ability to Remove or Add games?

Hi,

I wonder- do the "ODROID-GO ADVANCE" have the ability to Remove or Add games?

I want to buy it as a gift for my son, but i want first to know if it has the ability to delete/add more games into it.

I have MCITP and Programming background.

Big thanks!
Rami

Game ROM files must be stored in the microSD card.
But you need a Linux PC to access an EXT4 partition at this moment.

We eventually make a way to copy ROM files from a USB storage or remote scp via USB wireless/wired adapter.

@odroid Here's an idea. Have a startup script (called by systemd), (or called by udev whenever a usb filesystem is mounted), or a part of tobetter's odroid-config that calls rsync and copies over new stuff from the usb drive to the sd card automatically. It will be fast because it only copies over new content, doesn't delete stuff from sd by default (so you can add only one game in /roms and it will get copied on boot).
The script could use the status led or the screen to display progress...

There's no need for the average user to mount the sd card in linux.

That is how RetroPie does it. The script is here:

The ideal solution is a file manager. RetroPie uses Midnight Commander (mc), but its not well suited to the display size on GO Advance. Suggestions from the community for alternative file managers are welcomed.

Midnight Commander is based on the Norton Commander for DOS and is for non graphical interfaces (same as DOS) therefore it normally performs rather well on small resolutions.
I doubt there's much alternatives for it.
You can check here: https://www.tecmint.com/linux-terminal-file-managers/
but they mostly mimic the same look and feel.
Maybe nnn is an alternative, but it uses tons of key combinations same goes for ranger.
They are not very user friendly.

I think copying from USB to SD based on a startup script would be great, if the ROMs are correctly formatted it should only take a few lines of bash.

If the device had OTG it would be ideal.

I'm working on a file manager app that will make moving from/to a USB storage device easy.

Maybe the easiest way is to Port DinguxCommander: https://github.com/retrofw/dinguxcommander

I also thought about porting ogo-shell and adding file management capabilities but I am too busy at the moment.

That's a good idea Dinguxcommader is great and lightweight gets the job done duel pane views.

mc has a "learn keys" feature that can help you bind keys around.

As a Windows user, what is my easiest route? I was thinking of just plugging the microSD into my PC and loading games via a Linux VM in VMware. Any problems with going this route?

mad_ady · Post by **mad_ady** » Sat Jan 25, 2020 2:07 am

It should work, but you need to passthrough usb to the VM. Also you may need to do the copy as root to avoid permission issues

Network support was added to the latest reference image still in testing. This allows you to connect to the GO-Advance via wifi or ethernet and manage ROMs using a Windows compatible network share.

We've started testing this Paragon utility on Windows 10 to transfer/remove game roms to the EXT4 partition in the SD-card directly.
https://www.paragon-software.com/home/linuxfs-windows/

It seems to be working fine. We will make a wiki guide early next week after some more tests with our Ubuntu reference image as well as Batocera if there is no critical issue.
Note that the software is a shareware and the transfer speed decreased to 5MB/s after 10 days. I think it is an acceptable speed.
If you don't like that speed limitation, you have to pay $20 to buy the software probably or consider using a free Linux LiveCD on a VM.

BTW, we also tested "Ext2explore" and "Ex2Fsd". But they seem to support only EXT2 and EXT3 formats unfortunately and we tried the commercial Paragon program.

We've made a quick guide. The functionality was verified with our latest Ubuntu base image and it worked fine.
https://wiki.odroid.com/odroid_go_advan ... _game_roms

But the same instruction didn't work with Batocera image. The utility corrupts the Batocera root file system seriously.

It seems to have a compatibility issue with GPT things since our image uses a simpler MBR.
We need further investigation.

Have you tried DiskInternals Linux Reader with batocera?
Free version seems have no such stupid speed transfer limitations.

Also available as Total Commander plugin.

Post by **odroid** » Tue Feb 04, 2020 9:13 am

Linux Reader is Read-only access. It seems to be useless for our application.

The latest Batocera image also works with the Paragon software.

You have to boot the OS image on the OGA first before transferring game rom or graphic art files since the first booting process must run an EXT4 partitioning job and build the rom directories.

Make sure you unmount AND THEN verify the SD card both. Then you can eject it with the icon. Take it out of your PC, and roms will then show up. If you dont verify the roms may not show up. I have seen several posters mentioning their roms didnt show up, but showed up after I suggested to also verify. Is this a problem with the linux file system program?

Also mentioned on the linux file system forums: "I mounted an Ubuntu 18.04 Ext4 partition in Windows 10 as read only using Paragon Linux FIlesystem for Windows. Each time I do this, when I later boot into Linux, all files are changed in the file system to read only." https://support.paragon-software.com/sh ... rmissions-!!!!!

I have used diskgenius but unfortunately the version that allows for ext4 appears to be $99. Another option might be virtualbox.
