Hey there! As stated in the description:
Bosca Ceoil Blue is a modern port of Terry Cavanagh’s Bosca Ceoil.
It’s remade from scratch using all new technology, but it’s functionally the same. Current version is fully compatible with the original Bosca Ceoil, backwards and forwards. There are several usability and UI improvements.
And you can read here why I decided to port Bosca Ceoil.
