The catalogue still references V1.41; upstream V1.42 (published 10 Oct 2026) is not reviewed here. The V1.41 package has no campaign missions, campaign-location rows or mission-victory entries, and its source generator rejects the empty mission list. The pinned source defines 97 missions, 35,876 campaign reward-address rows and 97 local-victory addresses. World code also defines 185 Shop Mode addresses: 25 purchase slots, 20 stage-victory slots, 120 item-reward slots and 20 local progression markers. The 36,158 rows below are source/World address definitions, not active V1.41 seed checks. No seed or game session was tested.

Known scope and limitations

The V1.41 release contains launcher 1.41 and APWorld manifest 0.6.6 for Archipelago 0.6.8. The inspected APWorld has an empty mission-generation list and zero campaign missions/locations, although its tagged sources contain 97 missions. Its generator rejects an empty list, so new multiworld generation cannot proceed through that packaged code path. Wait for a corrected maintainer APWorld before starting a new room with this release.
Standalone play is a separate launcher mode. Use a dedicated, unmodified Mental Omega 3.3.6 Windows installation beside MentalOmegaClient.exe, Syringe.exe and gamemd.exe, and verify an original campaign first. The World packaging issue does not establish whether the standalone executable succeeds or fails.
The launcher generates loose mission copies and stores its state under RandomizerLauncherData. Custom maps, map packs and other gameplay modifications are outside the documented scope. Back up existing state before updating; some received rewards take effect on future mission launches.
Shop Mode treats a detected defeat, in-game restart or game-process exit without a victory marker as run failure. Its source retains permanent progression and AP received-item history, but current-run currency/purchases do not carry over. File replacement and receipt replay protections do not establish complete recovery from interrupted writes.
The executable includes a Bonus.mix archive and game-related icons. Their complete origins, redistribution basis and dependency notices were not established. This review makes no infringement determination. Source behavior and selected packaged resources were inspected; full executable-code correspondence and in-game compatibility were not verified.
