Metal Slug 4 continues the story of the fight against General Morden.

Debug Menu

おしながき

• メニューを　とじる（ＰＡＵＳＥしたまま） - Close the Menu (While Paused)
• ＳＥＴ　ＤＥＢＵＧ　ＤＩＰ
• ステージ　セレクト - Stage Select
• ＴＥＳＴ　ＳＴＡＧＥ
• サウンド　テスト - Sound Test
• リセット - Reset

It is worth noting this Debug menu is shared by Metal Slug 2, X, 3, 4, and 5.

To access the debug mode, open the game in Console Mode and set debug developer mode On at the Neo Geo boot-up screen: this can be done via the Kawaks emulator, the Nebula emulator or using the Neo Geo UniBios.

Start the game, and press COIN up during gameplay twice: after pausing, the debug menu will appear - with options to activate the debug dipswitches (which can be activated separately through other options using Kawaks) and even the ability to play on any regular level, and even some test levels not available in the actual game. There is also a Sound Test screen, and since this version of debug mode is carried over from Metal Slug 3, the Color Test menu is absent.

Unused Graphics

These 2 tilesets are present in the ROM respectively at 0x2690 and 0x2e00, and are supposed to be used to display the Parental Advisory Warning, but instead other graphics are used, which are totally out of place. (See Region-exclusive Messages)

Region-exclusive Messages

Depending on what BIOS is used, the message shown at startup will be different.

US (MVS)	Japan

How the screen should actually look like.

The character set normally used on the parental advisory screen was mistakenly replaced with the graphics for the character selection screens and Striker portraits from The King of Fighters 2000, rendering the screen a jumbled mess. This occurs with the MVS BIOS only, as the AES version skips it when booting.
