The Linux version is currently freeware and do not need a registration license to help the arbiters that cannot afford the cost of a FIDE endorsed program. This is my contribution to spread chess all over the world. The others that run tournament with paying players and get paid for their work, are expected to register a Windows or MacOS version to support the development cost.

The Windows and MacOS version of Vega (individual and team tournament) to administer more than 30 players needs a registration code. The registration code comes in a file that will remove the splash screen at the start of the program. Vega that you can download from this site is full functional although only for evaluation purpose, i.e. not to be used in real tournaments with more than 30 players.

The casual arbiter or teacher that needs to arbiter only scholastic tournament can take advantage of the educational license at half price.

The user that already registered a version for Windows (MacOS) can register for MacOS (Windows) at half price.

In order to run the pairing engine JaVaFo (AI Roberto Ricca) the user needs to install a Java Runtime Environment (JRE) at least version 7


It is NOT permitted to run the Linux version with an emulator/virtual machine running in Windows or Mac OS.
