The default Pico module comes with a 2MB flash memory
However, the rp2040 can use up to 16Mb using a W25Q128.
Can the interpreter use this extra space as drive A ?
Trying to avoid requiring an external SDcard.

I'm rolling my own board using a bare rp2040 so i can stick any QSPI flash there i want.

AFAIK the flash is allocated for the firmware, then the flash slots 0-3 then any remaining up to the limit is allocated to A:. I have some YD-RP2040 16MB clones that use the remaining available space so I assume that's how MMBasic handles it. :)
