Hmmsim Metro as Gaeilge

Yes, with Tranzio. Open Hmmsim Metro in it and look under its translations: every Irish version other players have released is listed there, ready to install in one click. If there is none yet, you can be the one who makes it.

Download Tranzio, point it at the folder Hmmsim Metro is installed in, choose a Irish translation and press Install. Tranzio puts the patch beside the game rather than editing its files, so switching back to the original is one click too.

Download Tranzio, add Hmmsim Metro from the folder you installed it in, and pick Irish. Tranzio lists every line of text, translates alongside you if you want AI help, and builds a patch you can play and share.

No. Tranzio is free to download, and installing a translation is free. Paid plans only add AI credits and team features for translators.
