Shadic is pretty much right. I don't think I'd be able to do stages anytime soon. Mostly a trial to see if this is any fun. If it is, I might keep working, but I don't think I'd actually be able to do stages, rather, find where the stages are. Even still, I'm making a custom corrupter to make things a bit easier. I want to make an editor to change all the graphics first, because the difficulty shouldn't be as high [hopefully].
SSB is 3D. Maybe the collision detection is 2D [best way I can think of it], but the stage is 3D. And smaller than a Mario Kart track. So it'd be easier, but take me MUCH more time because I have no skill with this. I think I'd rather use a 3D file inserter software than make a complete editor, really.
And that'd be awesome House. :D Viewer would help more, but if you can tell me how to run it on Vista [XP is fine if that's the only way you know], would be sveet.
If anyone wants to know about the corrupter, it'll have built in an original ROM and the modified one. I can restore modified to original, and even auto restore before recorruption. I can set ranges, set what it'll be corrupted to, and a series of boxes that state what to search for [that'll search for any grouping of values for larger number], replace all being default.
Dissambley isn't easy, or reading the disassembly isn't? Aren't there dissassembler software? [Can't get the one from Zophar's Domain working].
