Dreamcast games "finishing" before done

I have been trying to download dreamcast isos all morning but any one over 50 mb or so just stops downloading and says finished long before it actually is. I got crazy taxi fine but I have been trying to download THPS2 and a couple others four each times now, each time claiming it was finished at random sizes. I still have a lot of points but its really wasting thousands needlessly.

Is it me or you? Does this happen often?

Edit:
I have tried downloading them in firefox and google chrome, with and without download helper extensions

 

Have you tried using a download manager?

...I feel kinda dumb..I never noticed the Dreamcast section...oh well...I don't know if they're autoboot though. I don't wanna use the Utopia disc.

 

recommend any download managers?

most use the utopia disk it seems, but its not really much extra work for free games!

 

Downthemall for firefox.

Seems to be working much better

Welcome.

You can pause it whenever you want and it will resume where you left off.
