To reply to my own question.....
Project in question is a fork of another, the original author had not initialized the Pins for 1mhz and r/w in the main code, this didn't seem to matter on the RP2040, but seems to be what was stopping the RP2350 from working. ISTR that the power up (or reset) state of the pins is different. This would account for why it works on the RP2040 but not the RP2350.
Cheers.
