Updating a Sega Naomi 3.03 net dimm to firmware virsion 4.02 using netbooting, all programmes are freely available on the internet to download. I believe the 4.02 version allows you to use a card reader (Gd rom replacement) and allows you to use any CF card instead of official Sega ones, i dont have one so i cant say for sure.
i use the NetBootGUI launcher ...works fine,and i don`t need go to DOS (this is a a java program ...)
