CMDR-DOS：FAT32上的准将DOS 从流行的1541 5.25英寸驱动器到现代sd2iec SD卡接口，连接到Commodore 64串行总线的所有磁盘驱动器都使用Commodore DOS协议。CMDR-DOS是Commodore DOS协议的一种新的开放源代码实现，它使用具有FAT32文件系统的SD卡，并支持诸如分区，子目录和时间戳之类的高级功能，并且在65c02上运行！ 指挥官X16 它的内置的DOS 指挥官X16，并运行在主CPU上，所以籽粒API（ ，talk，tksa，untlk，listn，secnd，unlsn，acptr）ciout直接调用进入DOS执行。LOAD在8 MHz系统上，这允许大约140 KB / sec的速度。 演示：  成绩单： DOS"$=P":REM THERE ARE TWO PARTITIONS ON THIS SD-CARD 255 "CMDR-DOS SD CARD" MBR 1 "PART1" FAT32 2 "PART2" FAT32 READY.
