Hello, today I tried to use my old R4 on my 2ds but it didn't work. I used it a lot on my old ds (which is dead now unfortunately) but since I passed to my 2ds (in 2013) the R4 didn't work anymore. I asked a friend to help me and we tried to install the latest kernel for my R4 (we think it's wood 1.62) but it still doesn't work. Is there any way I can use it or it just cannot work on my 2ds? Thanks in advance for those who'll answer me.
