MemArena mmaps the emulated memory from a file in order to get the same mapping at multiple addresses. A file which, formerly, was located at a static filename: it was unlinked after creation, but the open did not use O_EXCL, so if two instances started up on the same system at just the right time, they would get the same memory. Naturally, this caused extremely mysterious crashes, but only in Netplay, where the game is automatically started when the client receives a broadcast from the server, so races are actually quite likely. And switch to shm_open, because it fits the bill better and avoids any issues with using /tmp.
Dolphin-emu - The Gamecube / Wii Emulator
==========================================
Homesite: http://dolphin-emu.org/
Project Site: http://code.google.com/p/dolphin-emu
Dolphin-emu is a emulator for Gamecube, Wii, Triforce that lets
you run Wii/GCN/Tri games on your Windows/Linux/Mac PC system.
Open Source Release under GPL 2
Project Leaders: F|RES, ector
Team members: http://code.google.com/p/dolphin-emu/people/
Please read the FAQ before use:
http://dolphin-emu.org/docs/faq/
System Requirements:
* OS: Microsoft Windows (XP/Vista or higher) or Linux or Apple Mac OS X (10.6 or higher).
Windows XP x64 is NOT supported.
* Processor: Fast CPU with SSE2 supported (recommended at least 2Ghz).
Dual Core for speed boost.
* Graphics: Any reasonably modern graphics card (Direct3D9/OpenGL 2.1, shader model 3.0).
