The GBAtemp Portal serves as the home page of the site. It can always be accessed by clicking the "Home" button in the Navigation bar at the top, or by going to https://gbatemp.net/. The features of the page have changed over the years, but in general it shows the latest news and reviews, latest discussions, occasionally a portal poll, and the Shoutbox (members with >100 posts only).
The original portal was a custom design made especially for GBAtemp. It was capable of listing the latest releases (back then for ROMs that were also hosted here) and the latest news. Every release got its own, separate box, so the page could get rather long at times when a lot of releases came out in a short span of time. This version of the portal was kept as the home page when the IPB forums were added.
A third design of the portal was released on June 14 2010 in preparation for E3 of that same year. The new layout was designed to fit more articles on less space, but also introduced new features, like the top 3 articles on the top and a like/dislike system. This version of the portal could also be customized, including the amount of news to be shown, and whether the releases box should be above or below the news box. This version of the portal was kept when the forum was updated to IPB 3.2 in October 2011.
On October 29, 2013, when the site relaunched on the XenForo platform after recovering from being hacked, the old portal layout was no longer available. Due to the limited time the staff had to port the site over to the new platform, it was opted to use the XenPorta v1 addon for XenForo. The page showed only the latest news items, all in their own separate block. A little while later, after the review center was re-added to the site, a box for the most recent reviews was added at the top of the page. This block also showed the latest scene releases from the partner site NFOrush, which was created by a GBAtemp member after the site itself stopped providing a release list.
