What about (save-image) for the Pico?

If there's a (room) function

While we’re at it, how 'bout a (save-image) for the Pico? There’s gobs of flash there and more
than enough for a copy or two of all the RAM on the board, no?

Unfortunately there isn’t an EEPROM library in the Arduino core, so unless someone else has written one it would be a case of starting from scratch.

The good news is that the Adafruit RP2040 Feather, ItsyBitsy, and QT Py each have an 8 MB SPI Flash chip which ARM uLisp already uses for (save-image) on their M0 and M4 Express boards, so that should be easy to support.

The latest version of ARM uLisp, Version 3.6d, now does support save-image on the Raspberry Pi Pico; see Raspberry Pi Pico.
