M3 simply download play problem

I have an M3 simply card and i want to download play games with my frineds who dont have it. Anyways, their screens get to a part it says Nintendo on the top screen but after that it freezes. Can some1 help me.

 

oh, also i did not trim the games. It might have been pre-trimed when i downloaded them. Do you know of a way i can check?

 

if it's not exactly 4MB, 8MB, 16MB, 32MB, 64MB, 128MB, or 256MB in size, it's trimmed. what game is it? where did you get it from? what is the file name? it shouldn't be pre-trimmed...
and did you guys try another location? my friend and i couldn't connect at this one place, but was able to at another.
also look here. it may help.

 

I want to do download play, not online (although in the future i might want to do online play).

 

oh and i got it at blackcats-games.com and the game is
Bleach DS - Souten ni Kakeru Unmei.

 

I also just checked and the file size is exactly 128MB. And it wont download play. So can you help me.

 

this happend to me too, and people said first it because i trim the games, and when i redownload it, it still have the same problem. but jump ultimate stars, and EBA, i trim it, and it still let me play single download card. but MPH, and club house, full version, won't let me play single download play.

 

so is there any info that would help plz?

Hellooo.... People i need your help here.

 

for god sakes people, is there any1 here who can help me?

 

I tried to get help on this awhile back ago, and never got help.

 

download play isn't guaranteed to work on most games. Why? RSA security has been stripped from ROMs. Without that security.. the DS will reject most games. Small games like tetris can get through though.

 

ok, thanks!
but why would the RSA security be removed?
