Welcome to the documentation for the IDE simulator!

The IDE simulator can effectively replace CD and DVD-ROM drives in legacy computer hardware such as PCs and arcade PCBs by allowing you to use an SD card or a USB flash drive containing ISO or BIN/CUE files. With no moving parts, less power consumption than an optical drive and a small profile, it can be installed in place within the device enclosures without any impact to performance.
