Installation guide: =================== 1) Unzip the engine in one directory, for example, "C:\Program Files (x86)\Arena\Engines\Ghost2". That directory should contain four files: - cygwin1.dll - ghost2_win64_v2_0_2.exe (or the 32-bit version) - kp_kp.gbb - kpp_kp_ram.gbb 2) Install the engine in Arena: - Engines -> Install new engine: Select "ghost2_win64_v2_0_2.exe" from the Ghost installation directory Before you can play against Ghost, the engine needs to be configured, first. 3) Configure Engine Arena automatically detects Ghost but assumes that it is Ghost 1. In the engine configuration, overwrite the "Command Line Parameters": Examples: "--xboard --hash trans 2G" (2 GB memory for transposition tables) "--xboard --hash trans 32M" (only 32 MB if you are low on memory) All other settings should be OK. Arena automatically sets the "Type" to "Winboard", which is fine. The engine is now ready to play. 4) Tablebases (optional) Ghost supports Nalimov tablebases. Use the "--tb" command to enable them but you have to translate the Windows path to Cygwin compatible syntax: For example, if the tablebases are located in "J:\path\to\nalimov\tablebases": "--xboard --hash trans 2G --tb nalimov 4M /cygdrive/j/path/to/nalimov/tablebases"
