SYSTEM REVIEW / 23 OCT 2026
BROWSER-LOCAL INTERACTIONS
MOMENTUM CORE / INTERACTIVE GUIDE

An arcade front door.
A system you can understand.

Your games. Your Linux arcade. Less setup. More PLAY. Explore how working setups become repeatable game packages.

A working setup, captured

ILLUSTRATIVE PACKAGE

Explore the parts of a package, then change a sample payload to see why fixed versions and exact bytes matter. These examples are teaching aids, not runnable installer files.

Your library stays yours

Momentum stores library data and play history locally. Downloads still make external requests. “No external tracking” does not mean “no network traffic.”

Approval is a trust decision

Package scripts execute as your user, without a sandbox. Hashes establish exact identity, not safety. Trust the publisher before approving execution.

MOUSE ARCADE / 0.2.2

L.A. Machineguns

Ordinary 1920×1080 fullscreen now matches the canonical laptop launcher. A bundled clean calibration seed initializes only absent isolated NVRAM.

Platform
Ubuntu 24.04 x86_64, X11
Runtime
Supermodel 0.3a-20260928-git-8b4de23
Input
Mouse aim, left/right click triggers. 3 credit, 1 start, Escape exit.
State
Existing NVRAM stays unchanged on upgrade, repair and reinstall. Older uncalibrated state may need manual AIM SET.
OPENBOR / 0.3.0 + 0.1.0

One build, two games

Marvel Infinity War and Ultimate Double Dragon 3 share the same exact extracted native OpenBOR 6391 runtime. Package preparation needs no FUSE or engine launch.

Runtime
openbor/builds/6391-ef96ad2e3a64
Marvel
Pinned author download or matching offline PAK
UDD3
Exact local UDD_3.0.pak, no download
Settings
Captured presets seed only when absent. Other controllers may need remapping.
SOURCE ACQUISITION / 0.3.0

Episode Enyo

The current installer does not bundle the mod. Reuse verified files/cache or approve the pinned publisher download separately.

Your data
Quake id1/pak0.pak + id1/pak1.pak
Runtime
Official vkQuake 1.36.0 AppImage
Host
FUSE2 and Vulkan loader prerequisites
Display
Fullscreen requested without forced laptop resolution. Wrapper accepts -window.
COPY-ONLY MIGRATION / 0.1.2

Virtua Cop 2

Copies media into ~/Games/virtua-cop-2 and leaves the previous game folder and separate settings/saves intact.

Inputs
Japan GDI and all 39 referenced tracks
Conflict
Does not merge into an existing destination
Acceptance
Owner reported successful gameplay on 15 October. Specific checklist items and other hardware are not certified.
MOUSE ARCADE / 0.1.1

Time Crisis II

Pinned MAME 0.289 with fullscreen, mouse aiming, BGFX default and an absent-only free-play seed. Supply your own timecrs2.zip.

Controls
Mouse aims, left-click fires, hold right-click for cover/reload; release to attack. Esc exits.
State
Public seed includes explicitly approved calibration, scores and bookkeeping. Existing state always wins.
Evidence
Existing-MAME installer lifecycle passed. Owner accepted the matching candidate and reported a perfect launch of the public package. Synthetic acquisition tests are not real network-download evidence.
Limits
No full-speed, campaign, other-machine or universal input claims.

Evidence has a scope

Static checks, synthetic lifecycle tests, real runtime acquisition, owner-reported gameplay and full campaign completion are different claims. Exact compatibility evidence enables installation. Each player still confirms their own setup.

Brutal Doom 64 0.3.0 has synthetic installation/managed-engine checks but no reported graphical gameplay or save/relaunch acceptance. A published package is not universal certification.

Ten curated setups

PINNED SOURCE SNAPSHOT / 23 OCT 2026

The package store is one way into the library. Other Linux games can use shortcut import or a manual command. These cards describe current catalog records, not live downloads.

Duke Nukem 3D, Aliens: Eradication, Ashes 2063 and QBJ3 have historical packages/adapters, but are absent from this pinned ten-entry catalog. Withdrawal does not uninstall an existing game.

The runtime decision

SIMULATION / NO SYSTEM PROBING

Compatibility is exact and package-specific. An unsupported build is untested, not necessarily broken. Change the scenario to see the permitted path.

Shared engine files, separate game state

Managed Flatpak slots identify app ID, architecture, branch and exact commit. Each managed game receives a separate profile and a hash-bound launch helper. Existing personal profiles are not imported. Different slots may duplicate dependencies.

software/flatpak/<app-id>/<arch>/<branch>/<commit>/
state/<package-id>/<profile-id>/

Preparation can leave a verified engine behind if later game setup fails. Closing the UI does not kill an active Flatpak transaction. No automatic slot cleanup, engine switch or existing-game migration.

Since the first explorer

8–23 OCTOBER 2026

Source conflicts, resolved explicitly

Current manifests, code, catalog and dated evidence take precedence over stale summary prose. These documentation differences remain in the repositories; this review does not edit them.

Reproducible source snapshot

Launcher and authoring source remain private. Public catalog and game pages are readable without a GitHub account. Revision identifiers below pin the source used for this review. Private repositories require separate access; public hosting of this guide does not grant it.

Review scope: current source, release history, package manifests and evidence records. Release ZIP bytes were not downloaded/rehashed and games were not installed or launched during this documentation update.
