Thank you, though that is a LOT of tech talk for me..... it took me 6 months to work out how to download games onto the R4!!!

Use an Arm7 patch. It works for almost all games with that problem.

http://www.r4ds.cn/download/r4_v1.18_kernel.htmlI had the same problem so I just downloaded the file, decompressed it with the program 'WinRAR' and then copied and pasted the new files/folders onto my DS replacing the old ones.Now I can get brand new games working on my R4Hope this helps x
