2 days I've downloaded over 10 rom, and 9/10 are corrupted :'( .WHY ??? I just can't take it anymore ... Please help me.
Rom I've downloaded : 2234 - Rondo of Sword ; 2243 - Pokémon Mystery Dungeon : Explorers of Darkness ; 2244 - Pokémon Mystery Dungeon : Explorers of Time ; 2252 - The World Ends with You
Only "Rondo of sword" not corrupted 1 time
WHY ??? I just can't take it anymore ... Please help me. Thank you so much!!

What exactly happens? Do you extract them from their archive? If it says there's an error in extracting, that means it didn't finish downloading or it got corrupt during download.

If you use a wireless network then try using a wired connection instead. Corrupted downloads are often due to dropped packages and wireless networks are sometimes quite bad at that.

How do you know the download is corrupt? What happens when you try to open it on your flashcart device? As anandjones said, did you extract the ROM from the archive? One in two questions about ROMs are solved by installing WinRAR. ;D

what exactly happen: I used IDM to download it. When it FINISHED, I extracted it and BOOM, it show this :"! C:\Downloads\2244 - Pokemon Mystery Dungeon Explorers Of Time (U)(Micronauts).rar: CRC failed in 2244 - Pokemon Mystery Dungeon Explorers Of Time (U)(Micronauts).nds. The file is corrupt"
plus, i use the LATEST WINRAR to extract it and i use wired network
I 've tried to download again and again, and it still show that :'(
please help me
thanks for all your replies

Downloading again and again most likely wouldn't help as it's probably just using a cached version. Try using a different browser such as Firefox if you're using IE and Opera if you're using Firefox. I believe the last one who had this issue switched from IE to Firefox and it all worked out.

thanks, then may be I just have to use opera ...

... and it still doesnt work :'(
Please HELP!

This is so true, I downloaded Ninja Gaiden (U)(Xenophobia), I downloaded it for like an hour and after that I opened it using WinRAR and extracted the .nds file to my folder "NDS Games" and at the middle of the file transfer, it says that the file is corrupt, I think that the file has the problem, I use Mozilla Firefox, I have a wired connection and almost all of the 112mb games are corrupt. Please, I hope you resolve this problem because this is the only site that provides all of the Nintendo DS games. :) Thank you.

if the file extracted successfully the archive isn't corrupt.

Replying to #10

...then if the file extracted not successfully the archive is corrupt, right?
what are you say that for ?? ???

Yes that's what he meant. Or if the file isn't extracted at ALL.

It's corrupt yes, but not on our server, meaning the problem occurs during the download which is sadly out of our hands. We really do want to help here but there's not much we can do about it. =/

so sad to hear that :'(
anyway, thanks for all your helping 'til now

Aha
Now i know the solution
just use the latest IDM (5.12) and everything is OK ;D
