Ah. That's still more than even the largest commercial megarom, though, no? As far as I know, even Metal Gear 2: Solid Snake was a 512 Kb megarom, and it's only a handful of obscure European indie/homebrew releases that have ever gone beyond that. So it's still a pretty good deal, I'd say!
Koei did soms large ROMs, but if you're not into Koei games, that wouldn't be a problem.
Modern homebrew stuff exceeds the 1MB barrier once in a while.
The rest fits easily.
