This is a sub-page of Proto:Super Mario World 2: Yoshi's Island/ys romX 0/Graphical Differences.
The various level backgrounds are in varying states of completion at this point. Only about half of the final's backgrounds are present here.
Layer 2#
Use Pro Action Replay (PAR) code 7E017A?? to change the Layer 2 background, and 7E017C?? to change the palette.
Castle#

Proto |
Final |
|---|---|
|
|
|
Background ID: 00
Palette ID: 00
An alternate version of the castle hall background which lacks the sky at the top. Not to be confused with background 19, which is the final castle hall background.
Woods#
|
Proto |
Final |
|---|---|
|
|
|
Background ID: 01
Palette ID: 01
Completely different background, featuring very rough pastel hills. The final replaced this with another woods background.
Forest Hills#

Proto |
Final |
|---|---|
|
|
|
Background ID: 04
Palette ID: 03
The background itself is identical to the final, but the palette was altered to have pinkish grass at the bottom rather than green.
Bubbly Clouds#
|
Proto (Custom Palette) |
Final (Unused Background) |
|---|---|
|
|
|
Background ID: 05
(Palette ID unknown)
A strange background featuring soapy, bubbly clouds. Replaced with a completely different background in the final game, though it wound up unused.
Forest#
|
Proto |
Final |
|---|---|
|
|
|
Background ID: 08

A completely different, much scratchier forest background. The final one was remade completely from scratch.
Tropical Water Hills#

Proto |
Final |
|---|---|
|
|
|
Background ID: 0A
Palette ID: 0A
Another completely different background. This one uses similar tropical hills as seen in the final, but partially submerged in water. The water is animated in both versions.
Volcano Forest#
|
Proto |
Final |
|---|---|
|
|
|
Background ID: 0F
Palette ID: 0F
A radically different background. The earlier version definitely lines up more with the Layer 3 background with the same ID.
Crystal Cave#

Proto |
Final |
|---|---|
|
|
|
Background ID: 13
Palette ID: 13
Another revamp. The crystals have a sparkling animation, which wound up unused in the final game.

Proto |
Final |
|---|---|
|
|
|
Background ID: 14
Palette ID: 14
The background in the proto is actually identical to an unused Layer 3 background, which is also present in this build as well. The final replaced this with the wooden cobwebs background.
Layer 3#
There are comparatively fewer differences in the Layer 3 backgrounds. Use Pro Action Replay (PAR) code 7E017E?? to change the Layer 3 background, and 7E0180?? to change the palette.
Flower Garden#
|
Proto |
Final |
|---|---|
|
|
|
Background ID: 1B
Palette ID: 13
Its details are much simpler, and there is also a type of X or white flowers that do not exist in the final version. The palette of the bushes is different, being orange instead of green.
Tower#
|
Proto |
Final |
|---|---|
|
|
|
Background ID: 18
Palette ID: 11
Layout is nearly the same as final, but the walls, bricks, and clouds are less detailed, only one tower is present, the little stars are missing, and the palette received a complete overhaul.
