The ICU games archive has been updated and significantly expanded: see the notice and article on the ICU web site.
Among other items, this update includes the IRLchess games collection as it stood at the end of 2017. Going forward, any games on this website will appear in due course in the ICU games archive also.
The article on the ICU website was corrupted slightly while being uploaded: it seems the ICU system processes and modifies web pages while accepting them. The original, including links to the two pgns files referred to, can be viewed here.
