Proto:Super Mario World 2: Yoshi's Island/ys rom 0 D/World 6

This is a sub-page of Proto:Super Mario World 2: Yoshi's Island/ys rom 0 D.

This article has just been started and needs the article basics added. Help us out and add them.

This page is rather stubbly and could use some expansion. Are you a bad enough dude to rescue this article?

This sub-page details all the levels of World 6.

World 6-1

Slightly modified version of the level from the previous prototype ys_romX_0.

World 6-4

This level differs from the previous prototype in that the vertical pipes now work correctly, and the camera on the "floors" is now blocked. Also in one niche, instead of a cloud with a question mark where the key was, there is now a wooden box, also with a question mark, which was not used in the final version. The penultimate room has no background and the final room is empty, however the camera is now blocked on a certain "section", causing Yoshi to now fall to his death upon entering it. If you activate the "free flight" mode, you can see a copy of the layout of the penultimate room at the top at the end, but it does not have collisions, which makes it impossible to stand on it. The level is still impassable.

World 6-6

Despite a complete overhaul of the sound driver, this level inherits a glitch from the previous prototype in the form of a lack of musical accompaniment in the second half of the level, similar to the second part of 6-2 of the final version, only with different graphics.

World 6-8

A very broken and unfinished castle level where almost no single enemy uses the correct graphics and even the background glitches out of existence.
However, between ys_romX_0 and this build, the devs decided to repurpose the first few screens of the first area as a testing ground of sorts, where various doors and pipes lead to various bosses and test rooms. It persisted in this testing role all the way into the final game!

This test room (originally World 4-1 in the ys_romX_0 build) tests out all the bonus games in this prototype, even the ones that ended up unused, like the house bombing bonus game or the minecart egg deployment bonus game.

Through other rooms you can get to the levels, which are the prototypes of levels 3-Extra and 4-Extra.
