There was a serious bug in the Ever17 converter that prevented entering the Sora route through normal means (you could still skip to it through the debug menu, but that forces you into a bad end). I also integrated the voice clip conversion instead of requiring a separate program to extract them.
Ever 17 2012/10/06 — v1.1.0 – Voice data no longer requires external KTG tool to convert – Sora route was inaccessible through normal means due to a bug.
Never 7 uses an earlier version of the same engine, but the bug only affected one minor branch when talking to Saki at the pool.
Never 7 * 2012/10/06 — v1.0.1 – Wrong branch was taken during Saki conversation at pool.
