I've been working on my sisters DS. A little back story, my old DS broke and I got a DSi to replace it, giving my old R4 to my sister. When I got my AceKard2i, the guy gave me an ezflash 3 in 1 for the DS Lite. Well, after shaving down plastic from an old GBA game I never play or care about losing, I finally transferred the innards of the 3 in 1 to a GBA cart and got it to fit and work inside my sisters DS. So, I backed up my DS browser to her R4 so she could use it all the time, however, it doesn't seem to want to work with the 3 in 1 (I got it to work once and only once). I've heard there's a patch to get this to work, but I've been unable to find the patcher. So I'm wondering how anyone else got the web browser to work with the 3 in 1. Everything else seems to work properly however.
