New Wine 11 engine, x64-crossover26.3-r11, with two fixes for bugs that only show on a Mac.
The Last Flame's Start did nothing (#99). After a file call the game asks Windows for its last error, and Wine on macOS keeps that value in a different thread slot from the one MSVC-built code such as Unity's Mono reads, so a missing save file came back as a stray pointer and the click ended in an exception. r11 keeps the two slots in step. The same bug can hit any Unity game whose error paths read GetLastError directly.
Videos a game plays through Windows Media Foundation and hands to Direct3D 11 as shared textures now reach DXMT with a real shared handle (the fix Proton carries). The Last Flame's menu video plays.
The Last Flame's page names the engine, so pressing Play offers it. Verified with the free Prologue on an M1 Pro: menu, run start, first fight, quit and save, on DXMT at about 86 fps.
A fix that needs an engine your Highball does not ship yet now says so and points at Check for Updates, with the option to play without it, instead of launching on the old engine as if nothing had asked.
r11 is a pick under Advanced or an offer from a game's page, not the default engine. Nothing changes for environments that stay on their engine.
