Making Advance Wars work With EZ-FLASH IV cart

Advance Wars does not work with the standard EZ-Flash loader. You need to use GBATA instead. The link below explains the steps requred.  To summarize: use GBATA's SRAM patcher on the .GBA file first, and then use the EZ-Flash loader to copy the .gba file, taking care to un-check the patch save box.

The question this raises: is there ever a time where you should use GBATA first? I don't know yet.
