Guys I tried to use the Retrogamefan system in my r4i3d but probably did the wrong way, now regardless of the system that I put the DSI does not recognise the R4, I lost the card? My DSi is in the 1.4.5 version
I may try the new ram site, and download more RAM to my Switch. Not sure if ddr3 is the right ram
for it tho. Edit- no it uses floppy Ram, just like @AncientBoi
