RetroAchievements Can Now Be Tracked on an Original PlayStation 2

Retro game achievement hunting has largely belonged to the emulation world. Players who wanted modern-style goals, challenge badges and a persistent record of their accomplishments in older games generally needed to run those games through compatible software on a PC, Mac, Linux machine or dedicated emulation handheld. A new alpha-stage project called xeRAbora, created by hacan359, is aiming to change that equation for PlayStation 2 fans.

The program enables RetroAchievements functionality while a game is running on an actual PlayStation 2 console. Rather than emulating the PS2 itself, xeRAbora works alongside Open PS2 Loader, commonly known as OPL, and a companion application running on a computer connected to the same network. The result is a setup in which original PS2 hardware handles the game while the PC monitors relevant game memory and communicates with RetroAchievements.

That distinction is the feature's biggest appeal. The console remains the machine playing the game, with all the familiar characteristics of original hardware, while the computer handles the tracking work necessary to recognize achievement conditions. When a requirement is met, the system can register that progress with a player's RetroAchievements account and show an unlock notification.

How xeRAbora brings achievements to real hardware

Achievements have become a standard part of contemporary gaming, whether they are called trophies, achievements, challenges or something else. They can encourage players to experiment with unusual mechanics, investigate optional areas, complete demanding tasks or revisit games from a fresh perspective. RetroAchievements applies that same idea to older titles, often building structured sets of goals around games that originally launched long before platform-level achievement systems existed.

Until now, using those sets normally meant playing through an emulator that could expose the game's memory state to the achievement service. xeRAbora uses a different arrangement. The PS2 runs an OPL-based application called OPL-RA.ELF, while the xeRAbora client runs on a PC. As the game plays, the computer receives and observes the required memory information. RetroAchievements can then evaluate unlock conditions in much the same way it would during an emulated session.

In practical terms, the player is not replacing their console with a software recreation of one. The PlayStation 2 is still doing the work of running the game. The connected PC acts as the bridge that makes RetroAchievements tracking possible. The system can also produce the celebratory on-screen behavior many achievement hunters expect, including a gold flash on the television when something is unlocked.

That is a notable development for collectors and hardware enthusiasts who prefer playing PS2 games on the original machine but also enjoy the extra goals provided by achievement sets. It gives supported games another layer of progression without changing the core experience of using a real console.

What is required for the setup

xeRAbora is not presented as a simple plug-and-play retail accessory. It is currently in alpha testing, and it requires some familiarity with OPL, local networking and running a companion program on a computer. Players need a network-connected PS2 using Open PS2 Loader, plus a Windows, macOS or Linux computer on the same network.

The current release materials identify downloads for OPL-RA.ELF and the xeRAbora client. Windows users use xerabora.exe, while Linux users can use the provided Linux x86_64 build. The project supports macOS as well. OPL-RA.ELF is placed alongside the user's usual OPL installation and launched in place of the standard OPL executable.

Functionally, OPL-RA.ELF behaves like OPL 1.2.0, but it adds two RetroAchievements-related entries to individual games' menus. Those additions are used to test the connection to the companion client and to determine whether a selected game is recognized by RetroAchievements.

Notifications also need to be enabled in OPL. This is important because the RA menu commands return their information through on-screen notices. With notifications disabled, a player would not see the connection results or support information. After changing the setting, users are instructed to save changes and cold-boot the console. Notifications ship disabled by default.

Basic installation and connection flow

1. Download OPL-RA.ELF and the xeRAbora client appropriate for the computer being used.
2. Place OPL-RA.ELF in the same location as the existing OPL files, then launch it instead of the normal OPL executable.
3. In OPL, open Settings, then Notifications, turn notifications on and save the changes.
4. Cold-boot the PS2 after saving the notification setting.
5. Run xeRAbora on the connected computer and sign in with a RetroAchievements account when prompted.
6. Open a game's menu on the PS2, using Triangle, and select RA: test PC connection.
7. Use RA: check game support to see whether the selected game is recognized and has an achievement set available.
8. Start the game and allow the client time to begin receiving its first memory snapshot.

The PC client asks for a RetroAchievements username and password the first time it runs. It then stores a login token in the user profile. On Windows, that location is in the local app-data folder for xeRAbora, while Linux uses the application configuration directory. The password itself is not stored, which is a useful detail for anyone weighing the security implications of leaving the client configured on a personal computer.

Testing support before launching a game

The two new RA options in the OPL game menu are central to the experience. First, RA: test PC connection checks that the PS2 can reach xeRAbora. A successful result displays a notice identifying whether the client responded, the address from which it replied and the speed of that response. This gives users a quick way to diagnose connectivity before spending time launching a game.

If the PS2 cannot get an answer, the first checks are straightforward: make sure the computer and console are on the same network, and make sure the computer firewall permits incoming UDP traffic on port 18194. Because this is a network-based setup, local configuration is likely to be one of the more common hurdles during the alpha period.

The second option, RA: check game support, handles game identification. The console hashes the relevant disc image and asks the PC whether RetroAchievements recognizes it. The on-screen response can show the game's title and achievement counts, including the total available, the number already unlocked and whether the game is unsupported.

Supported games receive extra visual indicators in OPL: an RA prefix in the game list and a badge on the cover art. These touches are small, but they make the library easier to scan for players deciding which game to tackle next. More importantly, the hash check helps ensure that the game being launched corresponds to the version recognized by the achievement service.

What happens once play begins

After a supported game starts, xeRAbora is expected to show its first snapshot within roughly 30 seconds, along with the number of achievements it is monitoring. Achievement unlocks can appear in the xeRAbora window and on the player's RetroAchievements profile. The console-side notification behavior means the moment can remain visible where it matters most: on the display being used to play the game.

The appeal goes beyond simply adding pop-ups to old titles. RetroAchievements sets often create reasons to approach familiar games differently. A player might be asked to finish a section under a certain condition, discover an obscure secret, use a neglected character or system, or achieve an efficient completion. For long-time PS2 owners, that can make revisiting a well-worn library feel more purposeful without altering the game's original design.

It also offers a potentially attractive middle ground for players who use OPL and maintain a physical PS2 setup but do not want to move their entire experience to an emulator. The PC is still a necessary part of the arrangement, but the game itself continues to run on the console rather than inside the companion machine.

An early project with promising implications

There are important caveats. xeRAbora remains in alpha, so users should expect rough edges and should not assume every network setup or game configuration will work perfectly. The project's usefulness also depends on whether a given title has a compatible RetroAchievements set and whether the specific game image is recognized through the support check.

Even so, the concept is significant. PlayStation 2 hardware has historically sat outside the usual RetroAchievements route because achievement tracking has been tied so closely to emulators. A tool that connects original-console play to that ecosystem could make achievement hunting more accessible to a segment of the retro community that values real hardware above all else.

For now, xeRAbora is best viewed as an ambitious work in progress for technically confident PS2 players. If its alpha testing continues smoothly, it could become a compelling new option for anyone looking to replay supported PS2 games with modern goals, persistent milestones and the satisfaction of unlocking them on the console they were made for.
