Resolve the game through the Epic launcher's plaintext manifests: new External::Epic component, ProjectPlatform::EPIC, and RunInnerEpicChecks mirroring the Steam path.

Summary by CodeRabbit

  • New Features

    • Added Epic launcher support for launching games.
    • Detects installed Epic games by reading local Epic .item manifests and uses the discovered install path during launch.
    • Added an optional Epic app name setting to improve matching accuracy.

  • Bug Fixes

    • Improved launch validation with a clear error when a matching Epic installation can’t be found.
    • More resilient manifest scanning: ignores missing or unreadable/malformed entries without interrupting discovery.

Review Change Stack

Warning

Review limit reached

@Segfaultd, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 41 minutes

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

Poem

I hop through manifests, swift and bright,
Finding Epic games by filename right.
From ProgramData to launch prep glue,
A bunny says: “EPIC now works too!” 🐇
