adding the nds files?

when i copy the roms onto my 8 gb mem card some do not appear i put 20 on only 14 will show on my r4 when in the ds. but when on pc files appear to be 20 there. any ideas
?????

Describe step-by-step what you do from when you download the .rar file from RomUlation.

i unzip with win rar. then i put them into a folder with all my nds roms. then with a fresh formatted 8gb sandisk mem card i install the 1.21 firmware now tried the 1,23 and does the same. i at first made a folder called games then put the .nds files in there if i do 1 or two there fine when i do muliple drops there, there but only half of them when on the ds.

if you have the original R4 it will not support 8GB memory cards.

its an r4 sdhc got rev 3 on box ?????

then it is not an original R4 and should support the full capacity. Try reformatting your microSD card

yeah i have tried that sometimes i get like 90 files appear then i add a new rom and it wont recognise it?

You sure it's a .nds file, not an .nfo file?

Only some NDS ROMs have the .nfo file, so that could well be the case. Meaning only 14 showed up if he put on .nfo files. Since .nfo files don't naturally show up as a viewable file on the R4 unless you change the view of the extensions of files you see.
