Thanks Anton. I'm a DevKit owner. Is the name of the file I'm looking for "MEGA65 SD card essentials.rar", which includes the ROM?
Also, I assume the "ROM" is the .COR file you told me about prior and I don't have to copy that file separately? So I simply unrar this zip file into the root, overwriting the files that are there, and reboot, holding down "NO SCROLL" to flash the .COR?
