This looks like an overdump.

256 Mbit (E03E6796) >>> 128 Mbit (A4DAE90B) ???

The reason I'm not sure is that the end of the ROM is filled with meaningless garbage - unusual for a dumping device to create? So maybe the maker used a 256 Mbit ROM? I guess we'll know more with the next dupe.

Teh dumpers are friends of mine, and they didn't usually dumped GBA stuff. In fact, they also asked me some help, about the real size of this one, and gbata doesn't seemt to find any space to trim, so they supposed it was effectively 256 Mbit. Anyway they wasn't sure anyway, so if you all can say us, better to learn :)

I think Connie is right. I've taken a look into the rom and it's extremely suspicious that the "garbage" (which indeed doesn't look like the usual overdump garbage) starts exactly after offset 00FFFFF0. That means, if we trim the rom right after that hex offset it would lead to 128 mbit.

On the other hand we have to think about how this kind of garbage has gotten into the rom. Maybe a faulty dumper? I know a lot of roms and I haven't seen this before... :?
