Review: Good quality - Mayflash products are very good, and this series of adapters is no exception. My only criticism is the firmware update process. Even following all the steps, the procedure ended in an error. Luckily for me, the MF104 comes with a firmware that I didn't find listed on the website, but which provided support for Master System controllers.
Review: Old school - Works great!!! and a great blast of the past..... perfect fit easy to use and apply love it

### ⭐ Sort of Works
*by E***C on December 9, 2024*

I have it in the correct mode, latest firmware, and using a selection of joysticks. The joysticks work to navigate the Switch main screens, but they don't actually work inside of any games. Most notably, Atari 50th anniversary doesn't work, which is the main game that you would want to work.
