Fanatical like a Demon
Super Mario World: 30th Anniversary Edition™
A project 4.2 years late in the making!
Super Mario World: 30th Anniversary Edition has come a long way from it's initial release. Prior to the start of this hack I had absolutely no asm knowledge, no plans, and no clear end goal/vision. It was apparent when I kept thinking it was the "final" version there was always things to fix, add, or balance out. The hack ended up becoming an ambitious project I just wasn't prepared for. These days I just maintain the hack fixing any oversights (though today there was a change made that was not bug fix but more on that later). Maybe if I'm confident that there's nothing left to fix I'll submit it to the hack section but that's a big maybe lol. Over the last few months I have been working on implementing retroachievements into the hack and with C3 I'm hoping to reach the possibility of a bigger crowd in the hopes to help test this set. There's 205 retroachievements that are split between normal mode, hard mode, bonus content mode, and the arcade mode. As of the writing of this post, the hack has not been updated to the current version on the site so please do not use that version if you want to help test this set out. If you need help setting this version up to work with the set, let me know via dms or you can post here.
A full list of the retreoachievements and their descriptions can be found here. Their art is in the works right now which you can view below. Art by HyperRed. If you like his stuff, his dms are open!
Now for the recent update. Usually I don't add/change features anymore bc as stated before, I don't want to drag the hack and just want to maintain it and fix bugs/oversights, but recently Sonikku has ported SMB3 Bowser and added a ton of features to it and I was able to modify the hack to have this boss (long story short I lost all of smw 30's assets via usb failure and so I had to manually patch in this sprite as an asm patch)! You can check out his C3 thread right here!
Old version:

New Version:
If Bowser gets shot by a certain amount of fireballs or if he makes it past the first layer of bricks on the floor, he'll enter a desperate mode where he begins going all out. He starts out but spitting fire slightly faster, the fire begins going straight when it reaches your y pos (as well as not being spin jumpable), and his slams stun you (he also doesn't look around). Once he begins going all out he'll begin throwing hammers, can jump multiple times, and if stunned he'll spit a barriage of fireballs. His slams will not break bricks at this stage and will take 3 attempts each time to break one. Two ? blocks with fire flowers were added to help balance out the increase in difficulty. For the sake of not dying 2794638 times I made myself invincible to showcase the boss's actions.

After C3, the hack's thread is where more discussion will continue for the retreoachievements should you guys wanna continue helping out.
