v1.0.0

First release of the MoBetta engine for World of Warcraft 3.3.5a on Apple Silicon Macs (Porting Kit / Wineskin).

  • No more crash at character select. Wine emulates the x86 instructions Rosetta 2 rejects (ARPL and nine undocumented x87 opcodes)
  • ~170 FPS in a light view, ~140 at the Shadowglen inn (MacBook M3): x87sidecar for the game's floating point, Direct3D 9 straight to Metal through our mtld3d build
  • Nothing touches the game folder or the game process. All changes live in the Wine engine

Install

You need Porting Kit or Wineskin Winery installed, with a working wrapper (port) for the game. Installing one of them creates the Engines folder used in step 2.

  1. Download WS12WineCX26.3_Mobetta.tar.7z and SHA256SUMS, then in that folder: shasum -a 256 -c SHA256SUMS (must print OK)
  2. Move the .tar.7z, still packed, into ~/Library/Application Support/Wineskin/Engines/. Library is a hidden folder: if you browse to it in Finder, press Shift + Cmd + . (period) to show hidden folders.
  3. Quit the game, open the wrapper's Contents/Wineskin.app (right-click the wrapper app, Show Package Contents), Advanced > Tools > Change Engine Used, pick WS12WineCX26.3_Mobetta
  4. Start the game; the first start updates the prefix once
