they ARE about the same size as dreamcast games (when stripped) and the maximum size is 1.2 gigabytes. not much bigger than a dreamcast game. it would make scene to upload them. again when stripped NOT MUTCH BIGGER THAN A DREAMCAST GAME!!!
as I said in another thread, it depends on demand. There is more demand for dreamcast because you can run burned games on the original console with no modifications. It is not that easy with gamecube, and GC emulators are not particularly good. As it happens, we are in the process of adding GC games, it just takes time. Regardless, your point about them not being much bigger than dreamcast games is irrelevant. the fact is they are 1.2GB each and we don't have unlimited space.
