Fixes Windows game import for PE files whose sections overlap SizeOfHeaders, including GTA Vice City. Header and raw-section truncation checks remain enabled.
- Installs signed Wine ZIP bundles intact and verifies their signature after applying the external PearWine overlay.
- Resolves DLL, data and executable paths from the bundled runtime; recommends PearWine 1.0.1 and the signed MetalSharp fallback.
- Gives signed runtimes up to 180 seconds to initialize their first prefix, and waits for asynchronous registry writes after wineboot exits. Fresh-prefix initialization plus the game launch test passed in 39 seconds.
- Strengthens the opt-in launch test to fail when the game exits early.
Validation: 331 XCTest tests (20 optional tests skipped) plus 24 backup tests passed; targeted follow-up tests passed. The pinned signed ZIP, installed signature, real Vice City import and managed launch were tested on an M1. Visual gameplay is not verified because Computer Use permission was unavailable.
Download PearSilicon.zip, unzip, and replace PearSilicon.app. PearWine 1.0.1 installs separately through Settings → Wine.
