My first ASM Post. I am a noob of ASM so the asm file is short. But when you use Asar to patch it, well... Bowser will go nuts.
Feature 1: On phase 2, He charges near the ground. Feature 2: On phase 3, He glitches and trys to fly away until you need to reset the emulator or die by the mechakoopas. Feature 3: Bowser will rotate like sonic when he drops peach. Feature 4: The raining fire will drop faster. Feature 5: He will start the battle instantly.
And there you go.
A smw test file is included.
Rejected because it contains a SMW rom, please use a .bps patch instead if necessary.
