The gp32 supports both FAT12 & FAT16 file formats. Any standard SMC card reader for windows should work fine for reading & writing files on the SMC card. Note that file names can only be up to 8 characters in length, followed by a period, and 3 extension characters. Directory names can only be up to 8 characters long. The EMS 5in1 card reader from LikSang.com is known to work fine for gp32 SMC cards. There is also other SMC info that is read by using SMC command 0x90: The 1st ID byte identifies the manufacturer, being either Samsung (0xEC) or Toshiba (0x98). The 2nd ID byte tells you the type/size of the SMC (0x73 = 3.3V NAND 16MB / Samsung SMC) The 3rd ID byte, if it contains the value 0xA5, indicates that this SMC card contains a unique 16-byte SMC ID. Due to security reasons, Toshiba and others do not provide information for reading SMC IDs without first requiring you to sign a Non-Disclosure Agreement.
