So the other day I found a really old R4i flashcart at home that my brothers and I never got to work. For the last few days I've tried using lots of similar firmwares/kernels (I don't really know the difference between those 2 words) cause I just can't find mine. I've tried everything and it still shows the classic red "menu?" error. This is the info you can see on the card's sticker thing: "R4i Revolution for DS (NDSI/NDSL/NDS) www.r4i-SDhc.com.HK" Yes, the site is down. The only thing I could find from there was this http://prntscr.com/dfylx4 but it doesn't work. It's not on RetroGameFan's thread either. I've also tried using DSTT firmware/kernels and some that supposedly work for R4 clones but none of them worked. I've tried dozens of firmware/kernels these last days but nothing seems to work. I'd really appreciate if some of you guys could help me. Thanks in advance.
