Changing the bank of the 4X memory card by the blueretro adapter (ESP32) for sega dreamcast

[AUSAMA47]

Hi, i saw a video that someone put the 4x memory card of the dreamcast internally using a board from dreamcast controller and wiring the board to one of the 4 port of the DC, he also used an ESP32 to mimic the signal of the controller buttons (he didn't use blueretro) and used a wireless PS3 Controller to control the dreamcast and also changing the bank of the 4x memory by pressing one button from the controller, so is there any way to use one of the esp32 adapter pins as a button to change the bank of the 4x memory card? My idea is to wiring the 4x memory to the port 4 by using a controller board and just changing the bank by the adapter wirelessly. I hope it make sense .
