May be a stupid question. do we always have to make a patch of it? ( ͡° ͜ʖ ͡°)
Like let's say I release a hack only with a modded Data.rsdk provided to be replaced for the game's main folder.
Does it still counts as a "Rom"?

If I'm not mistaken, it is preferable to distribute as little of the original game data as possible.  Unless the modded Data.rsdk (I guess that's Sonic CD?) is almost entirely new data, you should probably make an xdelta patch.

I'd like to add that 99.9999999% of the files hosted on this site are patches *only* (and images of said patches) with readme txt files and such in the archives.

There are other sites that are a bit more leniant, specifically certain 'cave' dwellers of an awesome Sega Mega Drive RPG series, but they shall not be named.  ^_^

So yeah, you can try xdelta, ninja, or whatever other crazy formats they have now.

Thanks, XDelta it is.
