So I found this old R4i SDHC Happy Box Version 2.0. I can't seem to find the official firmware for it since it seems like the official links on the site have been taken down (http://www.r4isdhc.com/download_v2-0i/). Any ideas on how to get my R4 up and running? I'm pretty new to the flashcart scene sorry. I attached an image of the exact model of my R4i.
