nds

recently download a few nds games into my r4 but it appear as untitled and cannot play what could be the problem

did you extract them from the rar files?

yes extract them and they appear as .nds files but copy to sd card the screen will appear untitled. cannot play at all. only for certain games.

Try backing up and format.

also did that by the way i am using a 8 gb sandisk card.. found out that anything more then 4 gb and the games will appear untitled.

Are you using an original R4, or an R4 III? If it's an original R4, it only supports cards up to 2gb in size, in other words, a non-sdhc card.

the card appears as R4 sdhc but i knew its not original R4 anyway the firmwares inside my R4 appears to be the same one as the N5 firmware. I tried downloading the N5 firmware but my R4 cannot load wonder why too.

When you got your original R4 III firmware, did you get it from this site?http://www.r4iii.com/download.htmlIf not, you should wipe your current SD card and reinstall your firmware using one of the ver. 3.08 kernels in the link.
