This wiki page has been created by scouring the internet and putting all of the useful info about the SD2IEC device in one place. Links to the sources of this information can be found at the link section at the bottom of this page.
SD2IEC is a hardware mass storage device using an SD/MMC card and interfacing with the IEC bus. It is based on the ATmega644 microcontroller from the Atmel AVR microcontroller family. The most prominent use of SD2IEC is emulation/replacement of a Commodore-1541 disk drive for a C64, C128, C16, Plus 4 and the VIC-20.
Preparing the SD/MMC card
Your SD/MMC card needs to be formatted as FAT12/FAT16/FAT32. NTFS, ext3, HFS+ etc will not work.
There are a couple of menu systems that can be run from the SD/MMC card. This makes running .PRG file and mounting .D64 files a lot easier.
This program works as a program launcher for Commodore machines. Even if it was originally intended for a device with sd2iec firmware, it works also with any CBM drive (without sd2iec functions of course).
