Pdf of Smartmedia Card spec.

Because 5v Smartmedia cards are rare and I have a Roland MC505 that can use them, I am wondering if it is possible to create a hardware emulator using an Arduino.
RP2350. 5v tolerant IO if set up correctly, enough GPIO's and the PIO's to trigger everything at once, and more than enough speed to emulate flash.
Smart(sic)Media is just a NAND flash interface really.
