Bug Central over here, reporting back because leod complained at me enough to make me come over here
9-3 Reverse Universe
Going past this point, the game / emulator crashes (due to a corrupt sprite) like so.
9-7 EREHPS EHT RAEF
Fadein has glitchy sprites before completion.
The 'boss' fight is either broken or unimplemented, as killing the Nose with a throw block leaves you stuck.
All sprites are missing from section 3, leaving jumps like this
uncompletable without adding platforms (and the bells at the end are non-functional, so you also need to hack in a door)
Fourth section has corrupt Map16 data here, preventing the level from being completed (solid platform added in LM) - as well, there is no exit at the end of the section (it leads to level 1 anyway, so...)
5-4 Soaring Stronghold
Jumping up here (at the end of the level) dumps you
here, and you immediately fall and die.
Also minor nitpick, but Thwomps do not check both blocks underneath them for collision.
8-4 Musical Mechanisms
Moving geometry sometimes fails to crush Mario if it's going upward.
The level still has an 'S' coin graphic in the HUD instead of the SMWC coin graphic.
Infinite 1-up farming spot is bad m'kay.
Game still locks when hit while caped and offscreen.
Entering this level before any level that has a KooPHD in it causes them to load egg graphics.
The Nexus Cannon crashes the game after a while.
REASON FOR THIS CRASH (mind the debugging script):
Normal cannonballs fired by the boss, like this one, are deleted when they exit the screen as usual.
However, red cannonballs are NOT deleted when they exit the screen,
and continue existing in a sprite slot.
Eventually, the cannonballs reach critical mass, and we run out of sprite slots -
and then the game crashes. (It oddly does not crash when a new cannonball is fired
, it crashes shortly after the cannonball leaves the screen
Also obvious blind spot.
