ED Exo Compare 1.2.2 — portable

A journal-linked exobiology companion for Elite Dangerous. It reads your local journal, merges scans and organic signals, and predicts the candidate species on a body from FSS/DSS telemetry alone — with payout ranges, first-footfall tracking, a system map, a customisable HUD and a species encyclopedia.

This release is the single-file portable build. For the unpacked program folder plus the two console builds, see v1.2.2-zip — same version, same code.

Download EDExoCompare.exe and run it. Nothing is installed.

Achievements for every plant colour you sample, region by region; Crystalline Shards predicted; a much faster app; and new photographs from the Stellar Exobiologists Guild.

New

Achievements. A new Achievements window in the menu counts every plant colour variant you have sampled — a plant counts on its third sample, a legacy plant (Anemone, Brain Tree, Sinuous Tubers, Crystalline Shards, Amphora, Bark Mounds) on its codex entry. It opens on one card for the whole galaxy and one per region, each with its progress and medals; open a card for its achievements:

• Galaxy: End Game (every variant there is), one per genus, and one per rarity tier.
• Each region: everything found there, each genus, each rarity tier, and four that are not only about plants — a Sampler (one plant of each rarity), Stars (log a black hole, neutron star, white dwarf, Wolf-Rayet and more there), Worlds (Earth-like, water and ammonia worlds, gas giants with life…) and Sights (five points of interest in the region to fly to).

Every achievement has three steps: Bronze at a quarter, Silver at half, Gold at all of it. Variants never found in a region are left out of that region's sets. Everything is counted from your own journals.

Track one achievement. Its plants get a ★ on the species rows and cards wherever they would count, and a new Achievement HUD section (in the launcher's overlay list) shows your progress, which plants in the current system count toward it — or, for Stars, Worlds and Sights, what is left, with the nearest point of interest first.

Sights need the points of interest. They come from EDAstro's Galactic Exploration Catalog, which you download yourself under Points of interest in the menu. Until you do, the Achievements window says so.

Crystalline Shards are predicted. The rules were checked against every Shards body in Spansh's galaxy data (5,932 of them): at least 12,000 Ls from the arrival star, 20–273 K, icy, rocky or high-metal bodies, never around an O or B star or a stellar remnant, in a system with an Earth-like, water or ammonia world, a water giant or a gas giant with life. They are rare even where they can grow, so until a DSS confirms them they wait behind "show unlikely" unless nothing else fits.

Better

Faster. Opening a system is several times quicker (about 1.8 s down to 0.4 s on a big one), and live updates while you fly take a fraction of the time.

Predictions. Host-star rules now read the brightest star at the body rather than the one it orbits, which puts two Anemones back where they belong. White dwarf and Wolf-Rayet rows in the colour tables are read correctly, Amphora is recognised after a DSS, and systems looked up on Spansh now feed the scan details.

Fixed

• Pressure in the on-foot catalogue was shown in pascals; it is in atmospheres now.
• Billions are written with a capital B.
• The on-foot catalogue is written safely, so a failed write retries instead of losing finds.
• A few console commands (/import routes, overlay names) did not work.

The first start after updating re-reads your journals once, to count your achievements across your whole history.

Where your data lives

%LOCALAPPDATA%\ED Exo Compare\ — settings, your LAN key, your EDSM credentials if you add them, the species you have scanned on foot, your Fix corrections, the journal folder you chose, your HUD layout, where your windows were, the systems you looked up on Spansh (kept 30 days), the shared exomastery folder, and the prediction caches. Nothing of yours is kept in the program folder, so replacing it on an update loses nothing.

Your journals are read, never copied out. Uploads to EDSM, Canonn and EDDN happen only if you turn them on yourself. Looking a system up sends only its name or number to Spansh.

Windows will say the publisher is unrecognised. The executable is not code-signed, so SmartScreen asks first: "More info" → "Run anyway".

Licence

MIT. The species photographs are not covered by it — see NOTICE.md, which names every contributor and says which images are borrowed from the ED-DSN community and on what terms. The list of Frontier-populated systems and looked-up systems come from Spansh.
