The Sony Access Controller (SAC) works well on the Sony PlayStation 5 console. The SAC comes with a variety of different joystick toppers and button shapes and four input jacks for external buttons and joysticks. Since Sony makes the PlayStation 4 console (PS4) and the SAC, they could add support for SAC to the PS4 System Software. There is no indication when this will happen.
The MayFlash Magic-S adapter supports many other controllers including the Xbox Adaptive Controller and Sony DualSense Controller. But the adapter does not support the SAC yet. MayFlash Support stated they will add support for the Sony Access Controller to the Magic-S adapters.
This project uses hid-remapper and a MayFlash adapter to make the Sony Access Controller work on the PlayStation 4 console.
The PS4 does not have an assist or co-pilot mode but a DualShock 4 controller can be paired with the MayFlash adapter. The MayFlash adapter combines SAC and DualShock 4 controller inputs so they control player 1.
Make sure the MayFlash LED is dark blue for PlayStation 4.
Press the SAC PlayStation logo button to make the PlayStation 4 recognize the SAC.

When shipped from the factory, most of the SAC buttons do not work so this is required to use all buttons and input jacks.
