As far as I know there are only two ways of patching. One is crash-patching, it is meant for the oldest 64M cartridges none of the newer cards need it. Also there's SRAM patching, this is to make sure you'll be able to save. It changes the EEPROM saving into SRAM. But to be honest I don't think this is what you need. Can you be a little more specific on what error you get, is it in the writeprogram or somewhere else?
