Hey I've rgh'd a few xbox (16 MB over Lpt) in the past with the last failing due to the nand breaking which was a 256 MB jasper (would've been my personal rgh) now i have a 512 BB and i do not want the pleasure of waiting 3+ hours for a 64 MB dump (~9-10 for a full 256 MB on the prev one) since i have an arduino board (arduino is a "standard" development/Breakout for atmel Microcontrollers... if you didn't know then imho this may be over your head) i've seen few (less than 5 people) use this...
Reading 512 BB jasper nand over USB using Arduino Uno?
