Returning to an arcade with an Aime card is finally worthwhile for some SEGA fans. Following two weeks of disruption, ALL.Net has entered a new phase of its recovery. The Japanese company has started restoring online functionality across 13 arcade titles.

However, this reopening is taking place on a trial basis. While selected games are gradually recovering their connected features, others remain without a confirmed return date.

ALL.Net restores online play and card support for 13 SEGA games

On November 15, 2026, at 9:00 a.m. Japanese time, SEGA shared an update through its official arcade service information account on X. Following the partial restoration of its network infrastructure, the company announced a gradual reopening for selected titles.

The recovery allows players to access online services and use their Aime cards again. Specifically, the following games are included in this initial phase:

  • Ongeki
  • Card Maker
  • KanColle Arcade
  • SEGA NET Mahjong MJ Arcade
  • Uranai Collection Trotte
  • Initial D THE ARCADE
  • HOUSE OF THE DEAD ~SCARLET DAWN~
  • Hatsune Miku Project DIVA Arcade Future Tone
  • Wonderland Wars
  • Wonderland LIBRARY
  • StarHorse4 (scheduled to return at 12:00 p.m. Japanese time)
  • StarHorseParty
  • StarHorse3 Season VII GREAT JOURNEY

The games are coming back gradually, so availability may vary from one title to another. SEGA recommends checking individual game websites and official social media accounts for specific availability information.

Several popular arcade games are still waiting for their return

One notable aspect of this announcement is which titles are missing. Despite the progress, maimai DX and CHUNITHM are not included in the initial recovery phase.

Consequently, fans of SEGA’s rhythm games face different circumstances depending on their preferred title. Ongeki and Hatsune Miku Project DIVA Arcade Future Tone are returning, while others remain affected.

All other SEGA arcade titles covered by the suspension remain under maintenance without online functionality or card support. The notice only covers SEGA games.

Some Bandai Namco Experience arcade games also use ALL.Net. SEGA refers players to that company’s official channels for their status.

The ALL.Net recovery follows an investigation into unauthorized server access

The shutdown of SEGA’s arcade services began on November 1 at 3:00 p.m. Japanese time. One day later, SEGA Fave disclosed unauthorized access by a third party to servers associated with its arcade infrastructure.

Based in Shinagawa, Tokyo, SEGA Fave operates ALL.Net and the Aime card system. The former provides network services, while the latter allows players to access their stored game data.

SEGA Fave’s initial investigation had not confirmed any leak of customer or business partner data. Additionally, the affected servers did not contain payment information such as credit card details.

The suspension also affected dedicated .NET services, arcade location listings, PrizeON and SEGA Lucky Kuji Online. New SEGA ID registrations were interrupted as well.

This incident should not be confused with the separate SEGA newsletter email leak. That disclosure involved unauthorized access to an external service provider.

SEGA plans to provide another recovery update on November 17

Restoring selected arcade games represents an important development for regular players. However, SEGA continues to prioritize identifying the cause of the incident and restoring affected services.

As of November 15, there is still no estimated date for a complete recovery. SEGA has also apologized for the inconvenience caused by the prolonged interruption.

The next announcement is expected around 9:00 a.m. Japanese time on November 17. However, the company may publish information earlier if significant progress occurs.

For now, the ALL.Net recovery offers some arcade communities a welcome opportunity to resume their usual gaming sessions. For others, checking individual service notices remains the best option before visiting an arcade.
