R4Ultra 1.56 English



This is the latest kernel version of R4 Ultra flashcarts. Release date: 9/25/2010.

After that time, they didn't release any new version of their own kernel. Instead, they modified AKAIO, which supports new games:

The manufacturer's website had been shut down since January 2013.
