“I seriously doubt this is possible. The players ‘reads only’ from the card. You cannot transfer programming information from the card to the player.”
Years ago I had a Sonic Blue mp3 CD player. I upgraded the firmware on it by burning the firmware file to a CDR, then playing that CDR in the player. I see no reason why a flash memory card based player can’t be designed to install new firmware that is on a flash memory card. Think of how the Fuze for example upgrades its firmware. It just looks for a firmware file in the root directory. There is no reason that a flash card based player can’t look for a firmware file on the root of card inserted in the player. I don’t see much difference between the two.
