(It's my first instructable , and appologizes for my poor english !!)
When i see this two instructables :
i want to do the same think !
First , i want to do this with the gold cartridge of Zelda , but it's was too expensive and when i mean it was a sacrilege !!
i have a Mario Bros/Duck Hunt , so i decide to use it.
I use also for my project a small hard disk (20go) and a USB - IDE cable adapter (4.62 $ at ebay seller "keyhere" ).
