Why wont some Mario NDS downloads work?

Can anyone help??? Im trying to download Super Mario World and Mario v Donkey Kong, however, everytime I download them they never work but eveything else does. Does anyone know why?

what do u mean they dont work?

and on what, give details (i probably wont be able to help, btw *sheepish grin*)

They wont load onto the DS - I re insert the R4 but they aren't there :-(

as in, u dont c them at all? do other games give u problems?

No I dont see them at all - I press 'A' and they aren't there, but other games Ive downloaded are

ok...sorry, thats really diff from the problems i had, so i cant help u. this person named "celticlou" offered to help me out with my stuff just now, and he/she's still online, so maybe u can message him/her for help. sorry icant do anything, and good luck with it

Thank you anyway :-)

See here: https://www.romulation.org/forum/index.php/topic,3880.0.html , also I deleted your other thread since it's misplaced and irrelevant considering the games here does work.

Thank you, would you know why some work for my DS and others dont? Sometimes when I download mario bros it downloads a whole heap of other things on my DS like - ROMS <DIR> and saves <DIR> rather than the game. Sorry Im very new to this so Im unsure of what to do. Thanks

If you download it from RomUlation could you then link me directly to the info page of the game?
