Compatibility

AERR targets the current Drug Dealer Simulator build on Steam. Older DDS builds may still work — most of AERR reads stable UE4 structures — but we only test against the current build.

The matrix

The machine-readable version is at /compat. Each row is an AERR × DDS combination with a status chip.

Status meanings:

• tested — Maintainer has this combination installed and running without known issues.
• known-issue — Combination works with caveats. See /known-issues.
• broken — Combination does not load or crashes. Don’t use.
• untested — Nobody has reported running this combo. YMMV.

When DDS updates

If DDS ships a new build, AERR may or may not need updating:

• UI only — no AERR changes needed; older DLL just works.
• Game logic / save format — may need a new AERR release. Track on /changelog.
• Major UE version bump — likely a full AERR rebuild; could take longer.

If your combo isn’t listed

Probably fine. Open a report on the Nexus thread with your AERR + DDS versions and any error text, and it’ll be added to the matrix.

Reporting

The “Report compat issue” button on /compat opens the Nexus thread. Include:

• Your DDS build number (visible on the main menu).
• Your AERR version (visible in the overlay footer).
• Steps to reproduce if something breaks.
