Yoshi's Island has got some of the most beautiful graphics on the SNES. The sunset, which can be seen in certain levels in the game (e.g. 3-1, 6-1), is one of the most beautiful ones especially for being layer 3 image.
Note that to fully use this background, you need both, a sprite status bar and UberASM. The former because it fills the whole tilemap and the latter because of the (required) background gradient and parallax HDMA.
Tested with : Asar, Uberasm Tool, DKCR Status Bar, Minimalist Status Bar, SMB3 Status Bar and SA-1.
Great rip. That's sure tons of work to replicate this nice layer 3 from YI.
For this graphic, I easily recommend the SMB3 status bar, since it works the best. DKCR status bar I tried a bit, and it causes some weird bugs. Minimalist is a no-no. For anyone using the vanilla status bar, use the legacy version.
Also, for anyone using this layer 3, please make sure to read the readme, because there's a lot of invaluable information there about how to use it and how it works.
