What Games Are Compatible With 4DO Emulator?

Updated

4DO is an open-source, low-level Panasonic 3DO emulator for PC, Linux, and Android, built on the FreeDO source code. There is no single official compatibility list on the site. Instead, compatibility is documented through release notes: each version lists specific games that were fixed or improved, and the 1.3.2.4 release is the most detailed recent example. If a game you want to play isn't named in the notes, treat it as untested rather than confirmed working.

Games explicitly fixed or improved in 1.3.2.4

The 1.3.2.4 release notes group changes into core fixes, graphical fixes, and new options. The compatibility-relevant items are:

Game What changed
3DO Interactive Sampler CD (1–4) Fixed known freezes
Panasonic REAL 3DO Interactive Multiplayer Sampler Fixed known freezes
Twisted – The Game Show Fixed long boot time
Killing Time 2.2 Alpha Fixed freezes
Microcosm Fixed start screens; now described as 100% playable
Alone in the Dark Fixed fonts — text on books and similar elements is now readable
Dinopark Tycoon Minor graphical fixes, but not yet 100%

The notes also state that the Clio core freeze fixes "may affect other games too," so unlisted titles can benefit indirectly from a core-level fix.

What the Anvil BIOS support adds

1.3.2.4 added support for anvil-bios, with the Anvil chip emulated. According to the release notes, this is needed to run some games from the European region. So if a European title previously failed to boot or behaved incorrectly, Anvil support is the specific change to check first.

How to judge compatibility for a game not on the list

Because the site publishes fixes per release rather than a master list, work through these steps:

  1. Check the release notes for the version you're running, and for versions after it if available.
  2. Search the notes for the game title — fixes are named individually (as in the table above).
  3. If the title appears with a qualifier like "not yet 100%," expect remaining graphical or timing issues rather than a clean result.
  4. If the title never appears, assume untested. A core fix in a later release may still help, but that isn't a guarantee.

Known limitations to keep in mind

  • Dinopark Tycoon is explicitly described as receiving only minor graphical fixes and "not yet 100%," so it is a documented partial-compatibility case.
  • The freeze fixes are tied to specific sampler discs and titles; the notes don't claim they resolve all freezing across the library.
  • Compatibility statements here come from release notes, which describe what was fixed — not a tested pass/fail status for every 3DO game.

Practical takeaway

If your goal is to play a specific 3DO title, the fastest check is whether it's named in the 1.3.2.4 notes or in the notes for the build you have. Microcosm and Alone in the Dark are the strongest documented cases in this release; Dinopark Tycoon is the clearest example of a game that runs but still has unresolved graphical work.
