If your looking for a whole new experience, you won't find it here. The aim of this hack is to incorporate all the features from the gba version of the game, but without the screen crunch, shitty music, or washed out colors. Beyond that, I've also added in a few other features and some graphical changes of my own. Don't be alarmed, its nothing drastic.
-Green Mario has mysteriously disappeared
-Dragon coins, power ups, lives, and Yoshi coins save over power cycles.
-Beating any ordinary level for the first time brings up the save prompt, but just in case you beat all the levels without all the coins, re completing any ghost house also brings up the save prompt.
-That nifty progress screen from sma2 is available, just hit select on the overworld to see it!
-After you free a different color Yoshi in star world, he becomes available in top secret area and in places where you'd normally find regular Yoshi. You just need to have the right power up to get him.
-Certain graphics have been replaced with their Mario Maker equivalents.
-All level changes from SMA2 have been ported, however adaptations related to the GBA's smaller screen size were ignored, because unneeded on the SNES.

Apply it to a clean smw USA rom with a header. I have no way to get screen shots with my retro pie, so if you can take a few screen shots while your experimenting with the new features and post them here it would help me out a lot.
I took the level layouts from Lui's improvement hack (with permission of course), you can find his project here. (https://www.smwcentral.net/?p=viewthread&t=88187
My next goal is to add layer 3 backgrounds to every level possible. It gives levels a really nice sense of depth. The second thing I want to do is give dragon coins more of a purpose. As of right now, collecting them all has does nothing. I have options;
-I can create a custom level opened by collecting all the dragon coins, though lord knows it won't be up to Nintendo quality.
-I can re create one of the un-released Mario Advance 4 e-reader levels and have it opened by collecting all the coins, it's cheap and dirty but would get the job done and would be up to Nintendo quality.
-I could make special world inaccessible until all coins are obtained. This would be the simplest option, but I'm not sure it would please the people who've already beaten this game before.
