The cartridge reader I am selling was created/designed by Sanni and built by me. The product includes everything shown in the first product photo. A 64GB SD card is included. Please check the specifications of this product below. ● Cartridge Reader HW5 Cartreader V5 ● Firmware Ver 14.3 ● Compatible with Sega Mark III and MSX thanks to a custom-designed board. Also, the menu screen display has been changed to reflect Japanese cassette formats. ● Automatic voltage selection function (Vselect) Because the voltage specifications differ depending on the cassette, it is usually necessary to manually change it each time using a voltage selection switch. However, this product automates this, allowing for safe use. ● SA1 chip support Supports SFC cartridges that use the SA1 chip. ● Expansion of the 64 controller port You can check the functionality of the controller buttons and stick. ● Case [Gray] The simple frame distributed on the official website exposes the board, so I created a case that covers the entire body. ● USB Type-C compatible Please use a standard AC adapter to supply power. ● Operation test An operation test was conducted as shown in the photo. ※ Not compatible with overseas versions of NES and MASTER SYSTEM.
