Metal Slug Advance is basically a severely watered down port of a Metal Slug game.

Unused Sprites

There's a lot of unused animations for the player characters, mostly the likes of reloading and idle animations that would have been used for flavor.

To do: Get more of them and document them.

Tyra firing while crouching. This is impossible to do in the game.

As for Walter, there is also an unused firing while crouching animation.

An unused animation of Tyra checking her hair.

Unused Objects

A fair few remnants of the scrapped underwater stage remain, like the Slug Mariner, squids, floating mines, and perhaps more.

To do: Same thing, rip them and write about them

Submarine Slug

Evidence that there was once an underwater level in the game, before they scrapped it and so on. It even has all the necessary animation for being used in the game.

Submarine Enemy

Another leftover from the underwater level, this time it's a squid from Metal Slug 5. It has all the animations, including exploding in a gory fashion.

Debug Mode Leftovers

There's a few textual remains of a debug mode, most of it nigh-identical to that of the arcade games, as well as the numerical listings of a stage select. Mission 3 has ten areas (only seven are seen in gameplay, including a cutscene) and Mission 4 has seven, meaning two areas aren't accessed.

Unused Text

In every version, at 0x797B0, is text for what looks to be a country selection, yet remains unused.

Regional Differences

The title screen in the Japanese version has the katakana text "メタルスラッグ アドバンス", which means "Metal Slug Advance".
