`Run-time error '76': Path not found` on finishing a game. Error 76 is VB6's "path not found", and the path it could not find was the game's own. Confining the prefix removed `z:`, which left `C:` as the only drive — and the executable was in the plugin checkout, which `C:` does not cover. So wine gave the game `\\?\unix\home\pastilhas\...\Minesweeper X.exe` as its own location (confirmed with `winepath`), VB6 file I/O cannot write to a path of that shape, and the first thing that needs to is the auto-saved recording. Which happens at the END of a game, so the failure arrived after somebody had played. The comment in prefix.ts already claimed "the game keeps its own directory, its settings and its replays". It did not. It does now: `installGame` copies the 68 KB executable into `C:\Minesweeper` on every start and the game runs from there, with cwd set to match so relative writes stop landing in C:\windows. Copied rather than symlinked — a symlink out of drive_c is a door out of the prefix, which is the exact thing confinePrefix exists to close. The cost is that replays now live inside prefix/, so deleting it to unwedge wine takes them along; that is in the README rather than left to be discovered. Verified end to end rather than by inspection: set Auto-Save Recording to All, played a beginner game to a loss, and `Beg 1.16 - Aug 23 2026 22.09.18 PM (Lost).mvr` appeared in C:\Minesweeper. Before this, that same moment was the error box. The default is "High scores", which is why an ordinary losing game never reproduced it.
