Altered U10S — change log

Generated 2026-09-27 16:42Z. One file per alteration; one line per map per published version that changed something in the MAP itself (blocks, items, physics) since the previous version.

How to read a line: U10S_26 — 09-20 · after last wipe · 2 changes: custom items / custom blocks (1: …) means: on Sept 20 the published Wet Wood 26 was replaced by a version whose custom block changed, the records were NOT reset for it, so the records on the board were driven on the previous version. wiped marks the version where the records WERE reset (new leaderboard).

What counts as a change: the physics fingerprint of the map — every authored block (name, variant, cell, rotation) and every embedded item's collision hulls per placement. Thumbnail-only, name-only or lighting-only republishes are not listed. pillars (not driven) are generated filler pillars re-emitted by the converter — visual, never touched by the car.

VLC and negative Matroska SimpleBlock timestamps — where it lives and how it got there

Context: https://x.com/vanilagy/status/2095904592307355834 — a Matroska file whose SimpleBlocks carry a negative 16-bit timestamp offset makes VLC show 351909:41:29 as the playback time.

TL;DR: the tweet's diagnosis is slightly off. VLC (via libmatroska) does read the SimpleBlock offset as a signed int16. What it doesn't handle is the resulting absolute timestamp going negative: that value flows through an unsigned uint64 API, wraps to ~2⁶⁴ ns, and that is exactly the number on screen.

Where it is

VLC doesn't parse block headers itself; modules/demux/mkv/ hands the bytes to libmatroska and asks it for the absolute time.
