Using Flash as EEPROM inMC9S08QG8

In her post Peg has explained how to use a bank of Flash in the QG8 as EEPROM and I can do that without a problem if there are only a few bytes that need to be saved as if it were in EEPROM. However, what if you need to have a fairly large amount of data, say 300 to 500 bytes, in a pseudo EEPROM area? There is not enough RAM to save a copy of the data. I suppose you could use another bank of Flash but I don’t have another 512 bytes to spare.

Does anyone have a method to solve this problem?
