Automatic Core Updater (windows)

I wanted to share my powershell script that automatically fetches the list of cores and downloads the ones that are updated in the server, it assumes you have installed Retroarch to it’s default location, but if you didn’t change $cores_path and $logfile to their appropriate location.

  • Run it by right click it and select “Run with powershell”.

  • If you are asked for confirmation for security reasons type: yes

NOTE: the first time it runs it will re-download all your cores, it’s normal. (only the first time)

If you want to make it a scheduled task the security warning may be annoying, you can bypass it by making a batch script with this code:

powershell -noprofile -nologo -executionpolicy bypass -File RA_cores_updater.ps1

No more to say, here is the Link to the Retroarch Automatic Core Updater for windows (Right click it and “save as”)


Thanks for this. When I initially ran it, the script wasn’t able to connect to the buildbot website to download the timestamps. I had to replace: Start-BitsTransfer -Source $cores_url/.index-extended -Destination $cores_path\ -TransferType Download

With this:

Invoke-RestMethod -uri $cores_url/.index-extended -OutFile $cores_path\

Which is a little odd since Start-BitsTransfer works fine when actually downloading the zips. But this was very helpful, thanks!

Just wanted to add a quick note to this.

First, thanks for the script! This is very helpful.

If your copy of Retroarch is installed anywhere but the default location, this doesn’t work. You’ll need to edit lines 11 and 12 to set the proper paths for the cores and output files.


Other than that, :metal: !

Works great! Just what I was looking for…

@Nadonate, do you know Stellar?

For sure! I use it to keep RA up to date. For updating cores, I was looking for something more automated.
