Talk:List of Super Mario World pre-release and unused content

Unusually Empty Areas on Main Map
The area to the west of Vanilla Dome above the Donut Ghost and Top Secret area is emptier then usual. Perhaps at one time there were some levels planned in that water area. LReyomeXX 16:04, 14 October 2009 (EDT)

Adding more pics
SO I can open the rom and such, but how do I tell what the hex code is so I can add the right level pics?
 * We definitely need more pics for "Unused Level Components". This article should help you--Holyromanemperortatan 17:15, 18 January 2011 (EST)
 * Lunar Magic and SMW Central are your friends for finding all the elements.

My Discoveries
Wrecking around with Lunar Magic with its Open Level Address function. Found some many levels not listed in the page: Level 0x30ADD: Same as Yoshi's Island 1, but the background is plain blue and there are no sprites, making this level unexitable. Level 0x20BCC: Unknown boss battle level. Methinks it's a leftover from the beta, probably Larry Koopa's battle where it would jump as seen in early photos. But it can be probably a boss battle's level address. Level 0x20ADC: Glitchy level with no layer 2 pointer compatiblity. Strangely enough, there are parts of Yoshi's House such as the chimney and parts of the tree (notable fact these are colored brown, because it uses FG Palette 4). Level 0x200: Another glitchy level beyond level 1FF. This one displays (i think) unused tiles. Level 0x30ADC: Scrapped and scrambled version of Yoshi's Island 1 (parts of that level are present). The end of the level is not changed at all (except the missing Giant Gate tape). Level 0x30336: Once again glitchy level. This has also the glitchy background object. Level 0x30000: Possible scrapped level. Unlike others, the player finds himself into water and immediately swim to not lose a life. However, path is blocked by a bicolored pipe. Level 0x30262: Gltichy vertical level. Level 0x20102: Empty void level. Level 0x52020: Same as above, this time there is a white background. Level 0x30256: Scrap of level 0x30263. Most parts are glitched. Level 0x5: Giant glitchy level. Interesting enough the Blue Switch blocks show out instead as mirrored blue Flowers. There is also and unused thingy which has as object command 2C and it's not accessible at all normally, neither in Map16. Level 0x10: Like as above: another unused object: object command 2D. It says it's reserved for 5-byte user defined objects. The other object (2C) also reappears. It is copied from level 0x0 to level 0x220. Also another unused object (object command 2F). It says it's highly unrecommended to use it. It appears to be a background ledge if displayed in Ghost Houses. Level 0x33333: Not glitchy at all. Just very few glitch tiles. Level 0x3233A: It's Donut Secret 1, but major tiles are deleted and there are some glitchy tiles. Level 0x30ADA: Yoshi's Island 1, with different palette for foreground and a block of Note Blocks at the very beginning of the level, placed up. Level 0x302C3: Glitched version of Level 0x302BD. Yeah, it's a big list, indeed. If anybody doesn't believe, go and check these with Lunar Magic's Open Level Address function and digit the address. Hope it helps!
