Update:

you talking about firmware.
This is tricky but the initial process would go something like this.

1. extract the original firmware (you may need to take the chip off the circuit board) by placing it in an eeprom programmer connected to your PC.

2. You will probably need to HEX edit.

3. flash the modified firmware back into the eeprom

In theroy yes you could find a bigger capacity chip and as long as you have the ability you could de-soledr the old chip and fit the new one, the hard part comes when you would have to re-write the firmware to utilise the bigger capacity chip.
