I did some house cleaning and I found this card.
webpage is www.r4i.ndsi.in (dead)
Latest kernel is supposed to be R4i3DSv4.2_EN.zip but the webarchive link doesn't work.
Not working link: https://web.archive.org/web/20150430123523/http://www.r4i.ndsi.in/download/3DSV4.2/R4i3DSv4.2_EN.zip
This boots on my 3DS so I would like to update it. If I can no worry, I have a working R4 and a crappy card with a timebomb that...
Yet another crappy R4 wannabe (r4i.ndsi.in) that I can't update
