ROM Hack Help with GBA VC Not Saving

[thedemonschild]

I've tried pretty much everything I can think of. I'm trying to get pokemon ruby version to save the game as a GBA VC but it always says The save file has been deleted. Please guys, I'm at my wits end over here. I downloaded a program that says it's a flash save type, but when I try to put that in ultimate converter, it doesn't work.

follow this guide

Note: it will say your files are corrupt and deleted after the title screen but it doesn't actually delete the save. just scroll through the text to reach the save.
