have you received your r4? or are you planning on getting it. usually when you get the r4, it comes with a disc, with files in which you simply drag and drop it into your micro-sd card. some files are not needed to use the r4 and are just programs to edit stuff. but i think now they do not come with a disc, and you just go on the r4ds.com website and download the kernel and moonshell stuff. then throw it in the root of the micro-sd file. simple as that, then the roms go anywhere . its relatively easy to get working, hope this helps
