So I've downloaded a US rom of Smash just to test some things while playing online. Anyhow, I've used my own header (can't remember from what game, but it was a Macronix make - C2), changed the manufacturer byte to AE (OKI Semiconductor, chip ID = AEF80290), changed the ending from 3ds to 3dz, and yet I still get this error. Any idea what's wrong? Using a Gateway by the way (and Gateway rom patcher for the header stuff). Edit: Oh wait, I think there are 2 versions of Smash with different manufacturers. I'll try the others too and update. OK, now I'm getting error 002-0120. wtf is that lol? it's not the banned error. Edit 2: oh OK nvm, it was all in Japanese so I couldn't read what it was saying, but using google translate it says that I gotta update to the latest version. Problem solved.
