Super Mario Advance
|Super Mario Advance|
Also known as: Chaoji Mario 2 (CH)
Super Mario Advance is a port of the Super Mario All-Stars version of Super Mario Bros. 2, with a few "new" elements recycled from the obscure BS Super Mario USA. Otherwise, it's just your standard port-of-a-port, which would be repeated later with Super Mario Advance 2, 3, and 4.
Mario's not the only one after coins, after all.
Super Mario All-Stars Leftovers
These graphics were unused in All-Stars, and they're not used here either.
The three orange tiles are パワ床 (instead of パワー床; POW Block), スイショウ (Crystal), and フラスコ (Flask), and mark where those graphics are loaded in VRAM. All other placeholder text from All-Stars has been removed.
Tiny Slots Icons
These tiny slot icons were discarded in favor of the larger slot icons.
The unused-but-updated tomato from All-Stars is still here, and the onion, which was used in All-Stars, is no longer used in Wart's room.
Several tiles from the NES version were revamped for All-Stars and ported over to Advance, but remain unused.
The mountain and cave tiles from the NES version.
The ice block that composed the terrain in some sections of ice levels in the NES version.
An unique type of rock, unlike any other in the game.
A non-animated and differently drawn whale tail.
A strange and somewhat crudely-drawn block.
Part of an alternate brick pattern?
These object graphics are loaded during world boss fights, and match up with Mouser and Triclyde (including the palette of the new snake). Given that Fryguy and Clawgrip have new boss intros, these were likely meant to be for the same purpose.
Two of the game's audio tracks are unused.
NES Boss Fight
A rendition of the original Super Mario Bros. 2 boss theme.
Zelda: Got Item
It's the Legend of Zelda jingle for picking up an item! Possibly used as a test track?
In the Japanese version, the cast roll is more or less the same as previous versions. International versions took the time to correct some of the enemy names, most notably Birdo and Ostro.
Game Select Sound
Unsurprisingly, the selection sound for the main game ("Super Mario USA" / "Super Mario 2") was also changed between the Japanese and international versions.
