While the Disk System was years ahead of its time in terms of a disk-format game console, the system and games both have reliability issues. The drive belt in the drive is a proprietary size, and standard floppy drive belts are too large. Until 2004, Japanese residents were able to send their systems to Nintendo directly for repairs/belt replacements, but Nintendo of America and the PAL regions do not service them (as the system was not released in those regions). Due to a flaw in manufacturing, the old belts have a habit of breaking or decomposing on occasion.
