Where to Download Project Eris and Project Lunar After the ModMyClassic.com Server Failure

Updated

Downloads and guides for both projects are still available. ModMyClassic.com states that active development on Project Lunar and Project Eris has been on indefinite hold for over five years, and that a server provider failure destroyed its main drives and corrupted the primary local webserver backup. However, the site also states that multiple smaller backups survived, all repositories remain available, and a live archive of the original website exists. The download links and archived guide pages listed on the homepage are the practical route to the files.

What is still available

According to the ModMyClassic.com homepage, the following links remain published:

Resource What it is
Archived Project Eris Page (Including Instructions) Original Project Eris guide and instructions
Project Eris v1.0.0 Full Package Download Complete Project Eris package
Project Eris v1.0.0 Desktop App Download Desktop application for Project Eris
Archived Project Lunar Page (Including Instructions) Original Project Lunar guide and instructions
Project Lunar Download Page Project Lunar downloads
Archived Website (2025 June) Archived copy of the original site, including original guides
RetroArch Cores (Direct from LibRetro) Cores sourced directly from LibRetro
Open Source Ports (Gitlab) Open source ports hosted on GitLab

The homepage also notes that all repositories remain available, so if a specific file is missing from the main download pages, the repositories and the June 2025 archived website are the next places to check.

How to get the files

  1. Open ModMyClassic.com and go to the homepage.
  2. For Project Eris, use the archived Project Eris page for instructions, then the v1.0.0 Full Package and Desktop App links for the files.
  3. For Project Lunar, use the archived Project Lunar page for instructions and the Project Lunar download page for the files.
  4. If a link or file is missing, open the Archived Website (2025 June) to reach the original guides and instructions, or check the repositories, which the site says are still available.
  5. For cores and ports, use the RetroArch Cores link (direct from LibRetro) and the Open Source Ports link (GitLab) rather than expecting them from the main project downloads.

Expected result: you end up with the Project Eris v1.0.0 package and desktop app, or the Project Lunar files, plus the matching instructions from the archived pages.

Common snags

  • A download link does not work. The site says the damage from the server failure was "somewhat minimal" but that it will replace missing elements only "as and when possible." Treat the June 2025 archived website and the repositories as fallbacks.
  • The instructions look outdated. They are. The site states the projects and the original website have not been updated in over five years, so the guides reflect that older state.
  • You expect new releases. There are none planned. Development is paused indefinitely; only the community side remains active.
  • You want live help. The site points to its Discord, which it describes as still active and driven by a friendly, supportive community, as the place to ask newcomers' questions.

Alternatives worth knowing

The homepage explicitly mentions that alternative projects exist, such as Hakchi, along with new projects that appeared after development paused. If your goal is simply to mod a mini system rather than to use Project Eris or Project Lunar specifically, those alternatives are worth exploring before working through archived instructions.
