I tested it works with GoGui on Windows and Quarry on Ubuntu.

GoGui

I used GoGui 1.5.1 on Windows.

GoGui with Egaroucid is something like this.

First, you have to register Egaroucid. Please add -gtp to the command, and set working directory as the directory on the executable.

Then you can execute Egaroucid.

On GoGui, board orientation is horizontally flipped, so you can see the ordinal board with flip the board horizontally again.

Quarry

Egaroucid on Quarry is something like this.

First, you have to add Egaroucid. Open Manage Engine List via New Game or Preferences. Please add -gtp to the command.

Then start game to run Egaroucid.
