Start up your Cas software, 8.2, click on the smartcard tab, top left.
Now click on the card programmer icon.
Insert your fun card, chip faceing down, into your Cas 3+.
It should automatically detect your card as a fun card, and give you the options of:
Click on the folder icon next to Flash Memory, navigate to where you have your funcard file and load the flash file.
Now click on the folder icon next to External EEPROM, navigate to the funcard file and load Ext Eeprom file.
Click write and it should programme.
It's been a long time since I've programmed a funcard, as they're not really used anymore, but that should do it.
Please post back if you have any problems.
