Super Mario World: Super Mario Advance 2

Super Mario World: Super Mario Advance 2 is the second installment of one of Nintendo's schemes to make us buy the same games over and over again. It's basically a port of Super Mario World with added voices, minor level changes, some additional cutscenes, and worse music.

Graphics
Most of the graphics in this port are marginally-edited copies from the SNES original, and as a result it keeps most of the original's unused tiles. The port actually found a use for some of the tiles it inherited, though.

Flying Birds
After finding all 96 exits, a cutscene plays where the birds from Yoshi's House fly. Their flying tiles exist in the SNES original, but were never used.

Unused Stages
Several of the unused stages from the SNES original are also unused here, although at least this time they can be accessed through glitches.

The glitch requires the ability to warp anywhere using the select menu. When Mario or Luigi is at Star World 3 on the world map, press Right while pressing Select simultaneously (actually, within the same frame). On the level select menu, warp to the second Star Road on the list. When Mario or Luigi stops moving, select the level and the unused level intro and TEST will be loaded. This is only one way to access the TEST level.

Unused Level Intro


One of three unused level intros in the SNES version, called Rope 2. It is largely the same as the original, except the No Yoshi sign is lower.

TEST


The same placeholder level as in the original game, except the background is glitched.

#2 MORTON'S PLAINS


Do the aforementioned glitch at Vanilla Dome 1 while walking down, and select Choco-Ghost House from the menu. Otherwise, it's identical to the original, except the level name is gone. The secret exit will take you back to Donut Plains 1 with the game reverted back to Summer (but no way to revert it back to Autumn and no way to warp), while the normal exit will cause the game to lock up after producing a ton of invalid "path tiles". wopimuKVqsQ

Sounds
Most of the sounds are either from the original game, or voices taken from Super Mario Advance, along with some new ones.

"Here I go! Super Mario!"

This sample (probably an earlier sample for the Game Select screen when choosing Super Mario World) doesn't seem to be used. In the final game, Mario and Luigi both say "Super Mario" and Mario says "Here we go" rather than "Here I go!". Interesting.

SMA2 Title Screen
SMA2 started the trend of completely redoing the international title screens of the Super Mario Advance games. Ours look completely phoned in by comparison.

Game Select Screen
The Japanese version uses a remake of the original Japanese logo, interestingly with "Super" above "Mario" like the Super Mario Bros. 4-era American logo. The rest of the world got a shrunk-down version of the international logo, which makes sense and maintains consistency with the original releases.

SMW Title Screen
...But not this. Despite going through the trouble of remaking the original Japanese logo for the game select screen, the international version is used on the Japanese title screen. At least the unique trademark symbol and original lighter-blue color were retained.

Music
The music played in the "96 exits" cutscene changed slightly between versions. The international song includes most of the stage clear theme from the original Super Mario Bros.
