So I found a code that'll allow me to visit places previously accessible...and for the most part, the worlds are complete, save for a few areas. While searching in a special world only accessible by clearing all the Star Road levels (and getting the secret exit in the TO BE CONTINUED level), I ran across what I think is the last level...and it's VERY similar to the last stage in Kirby Super Star (or Deluxe, in Japan), only it's more open. Surviving an area spotted with Paratroopas (by this point the special pallate has been pasted, so they are now Para-Mario clones) takes you to the hidden boss in the other Star Road, Nova's red cannons (Two of World 8's bosses also exist in this world, but the sprites are glitched). Just destroy all the cannons as quickly as possible. Beyond Nova...lies Marx's room...but Marx must be busy elsewhere, and does not appear to fight Mario. So, since Marx is in a hack called Mario Fantasy, I grab it. This is the battle that results.For me, Marx is fairly easy, he just takes a while due to his high health. I was surprised at the start, so that's why I got hit. I can't seem to grab the block he throws along with his cutters...but I can get the other two times blocks appears. Oh yeah, and to help avoid the laser attacks, the creator added a Balloon Mario effect that can be activated by pressing B again after jumping. Press R to deactivate it. So, with that, he roughly follows the same pattern he had in KSS, only he doesn't mix it up as much, and his "black hole" attack stops as soon as he disappears, making it rather worthless, IMO.Until Marx makes his entrance in Brutal Mario, the Mario Fantasy hack is the only hack he appears in. I am aware that someone put Marx in Brutal Mario, but it was custom, meaning the user probably made it himself. I don't know, just take my word that Marx is only in Mario Fantasy, and to get the hack to play him. Oh, and let's hope more bosses appear as well.BTW, I've visited every level, and some have new stuff, but they aren't complete.EDIT: In case you want to play Mario Fantasy, here's the link: http://www.smwcentral.net/?p=thread&i...
