Switch between Bone Beach and Sandfalls, filter verified Trinkets, bosses, train stations, and routes,
mark entries as found, and jump directly to the relevant guide or database page.
Accuracy rule:
this beta does not invent map-pin coordinates. A location stays in the verified
location list until its exact pixel position on the map image has been manually confirmed.
The data structure already supports pins, so verified coordinates can be added later without rewriting the tool.
Exact pins appear only after their image coordinates have been verified.
Use the location list on the right for the current verified sub-location data.
Coordinate helper:Click the map to read x/y percentages.
The calibrated beta starts with two regions and eight verified entries.
Bone Beach tracks Joule Syringe, Polyp Lamp, and Mined Mind.
Sandfalls tracks Niter Belt, Tunneling Codex, Sandy Station, Major Miner,
and the route transition into Bone Beach. Sandy Station stays under Sandfalls
even when a guide informally calls it the “Bone Beach Train Station.”

Add Pins Without Rewriting the Tool
Each location already has optional x and y fields.
Once an exact position is confirmed on the image, enter the percentages in
interactive-map-data.js and the pin appears automatically.
This beta uses the current Mina the Hollower Wiki/Manual as the factual baseline
for item, boss, region, and Coltrane Peak classification. GameSpot and a detailed
GameFAQs walkthrough are used for the Sandfalls TNT route, Sandy Station access,
and the practical transition into Bone Beach. Ambiguous transition screens are
treated as boundary notes rather than silently reassigned to a neighboring region.
