Signature Games releases are PAL.  We don't track PAL PS4, Xbox One, or Switch yet so we aren't adding these releases now.  When we do add those consoles we will add those games too.

Thank you

Here is the PAL Gamecube version.  We added this to the site about a month ago, sorry for not notifying you earlier.

The code for this is mostly done.  We are just finishing some tests and gathering some data for the charts.  It should be ready on the site first thing in the new year.

The capability to add these to the site is live now.  We are working on  getting more of these cart and disc photos (and circuit board photos too).

You can see an example of this here:

You can click '+ 2 more photos' link by the cover art or scroll down to to the images.

Contributors to the site can also add their own photos if we don't have them yet.

This should all be possible with our "Marketplace API".  We have different calls:

Publish new item (or edit existing one).  Be sure to use "is-collection" parameter.

Remove item

You can add lots of items using our import tool.  The API is meant for 1 item at a time type requests.

You need a subscription in order to make these API requests.  Cheapest costs about $4/month.

I hope that helps.  

If the collection tracker doesn't do what you need via API, then you can definitely use our pricing data only via API.

This is in process now.  We have a complete list on the site and we are gathering price data now.

The PriceCharting web app does not have a back button, but the browser you use to open the app will have a built in back button.  

Android:

Click the back arrow on the bottom of every app

iPhone:

Starting from just outside the edge of the screen, swipe from left to right to go back, just like swiping the pages of a Kindle book or an iBook.

We don't have a way to delete particular games in bulk.  You can delete your entire collection and add the Wii games only.

Delete collection: https://www.pricecharting.com/delete-collection

Or export your entire collection, delete all the games except Wii from the export file, then import on the Wii games.  This would be the fastest method.

Your comment has been migrated over.  Thank you.

You can do this now.  Just filter your collection by console and you will see the value of all the items for that console and all the individual items for that console too.
