JPN games like JPN-Poker and JPN-Cards require a one-time installation of a runtime before installation. This ensures smooth functioning of all JPN programs.
The reason behind this method is to create a powerful software package with a tiny size, ensuring your convenience and pleasure. It's worth noting that all future updates of the software will not require the 15mo runtime download. So, once downloaded, you can rest assured that you're ready to enjoy the whole gamut of JPN games without any complications.
