This is a disk system with a replaced belt and USB Type-C power conversion. No need for a bulky AC adapter. The internal belt has been replaced. The belt is not the notoriously unreliable Mobilon band. Flat belts are also not very durable. This time, I'm using silicone rubber, which is said to have a durability of over 50 years. Also, I've taken measures to prevent the belt from slipping off, which is a common issue. After the replacement, I've adjusted the head and rotation speed, and confirmed that it can read and boot disks with several game disks. Please note that disk reading may not be possible depending on the condition of the disk, differences in data writing methods, and the tendency for reading to be less reliable on the inner tracks. Therefore, I cannot guarantee that all disks will work. As a precaution, I'll include one of the disks I used for testing as a working example. Please use a proper charger for the USB power. If you're not using a wall outlet (e.g., a laptop), there's a possibility of insufficient power. I've confirmed that it works correctly even when connected to a USB-powered Famicom. If you have any other questions, please leave a comment. I will also be listing this on other flea market and auction sites, so it may be sold out depending on the timing.
