So I've been trying to get GiGaHeRz's Dev9 plugin to work of the last couple of hours.
Despite me having WinPcap installed, PCSX2 would always crash selecting and applying plugin selection settings, except when I used somebody else (portable) config files.
As it turns out, GiGaHeRz's Dev9 plugin looks for a folder called "Logs" in PCSX2's install directory, if this isn't present it will crash PCSX2, no warning, no hints as to what's happening (this folder is automatically created in portable mode).
If you have this issue, try creating a folder called "Logs" in PCSX2's install directory and you should be able use the plugin.
