Questions regarding the cable for vmu; I need one as well

[J!]

Any of you know where to get a cable for the VMU? I want to store my DC saves on my computer, but I don't know where to get one...

Also, what prog do u need to swap DC save files?
I know u can use Dexdrive's prog to do that for PSX...so after I get the cable, what prog do I need to put DC saves on my comp and download save from my comp to my VMU?
Please help!!
