ED Exo Compare 1.2.0 — 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 v1.2.0-zip — same version, same code.

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

Plant colours that match the game, your exomastery and codex in files you can keep and share, and a camera for branded snapshots of any panel.

New

Plant colours follow the brightest star in the planet's sky. For a star-coloured species, the game picks the star that shines brightest where the plant grows — not simply the star the planet orbits. A planet close to a brown dwarf keeps the dwarf's colour; one further out, or round a dim companion star, takes the bright main star's. The app now works this out from each star's size, temperature and distance, and for catalogue stars (HIP, HD and the like) from their real brightness. A planet round a pair of stars gets one colour instead of "Cyan or Orange". Checked against 13,000 codex entries from other commanders and every colour in the developer's own journals.

Colour tables from the game itself. Every species' colours now come from the game's own codex list: three wrong rows fixed (Fumerola carbosis, Recepta deltahedronix), 36 missing colours added, and species whose colours differ from the rest of their genus (all Aleoida under a Y dwarf, for one) have their own. Plants under a white dwarf or a Wolf-Rayet star show their colour instead of "unknown".

The colour you logged is the colour you see. Once you log a plant, its row and card show the colour you actually found. If the app had predicted a different one, a ⚑ marks it and it is written to the outliers file — for your whole history, not only the system in view — so every miss can be looked at and fixed.

Exomastery menu in the launcher. Refresh, Download my exomastery and Download my codex as files you can keep through a reinstall or give to a friend, and Open shared folder: drop other commanders' files in it and the app merges their finds with yours — duplicates compared, their species shown as "shared". The files carry your commander name (rename them if you like) and never your Frontier ID.

Snapshots. A camera on the Exo-signals card, the Candidate species list and the system map copies that panel as an image with the ED Exo Compare stamp under it — paste it straight into Discord. Shift+click saves a PNG instead. Options → Snapshot images adds your commander name, the system name and the time; all three are off unless you turn them on.

23 new species photographs, among them Bark Mounds, Electricae radialem in three colours, and Tussock capillum from CMDR PhoEniXDFA.

Fixed

A moon's logged colours showed on its sibling moons. Logging a plant on one moon made similar moons next to it show that colour as if you had logged it there too. Each moon now shows only its own.

Reloading the page after landing opened whatever body came first in your sort, not the one you were on. It now opens on the body your ship is at, then the one you target.

Re-uploaded the same evening: the Exo-signals snapshot camera sits right beside the [?] instead of on a line of its own, and the snapshot stamp names the project page, bahuckel.com/projects/edexo-compare. If you downloaded 1.2.0 before, download it again for these two.

The first start after updating re-reads your journals once, to apply all of this to your 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".
