In missions where you drop into the area via parachute, hold Left and fire. Technically, these were used in the game. Some of them does actually get used in varied ways, as will be mentioned below. Someone in the company seems to not want to let it go. This was axed for a simpler yet smooth set - and despite the fact that most are not used at all they all appear repeatedly in later games, to the extent that the same animation is made for other new playable characters and they still remain completely unused. However, the Girida-O palette won't change when its spheres get misaligned.įinish uploading the remaining sprites form here: Īt one point, the playable characters were to be more flexible with varied movements. If there is a Girida-O in the screen, it will also show its 3 sphere sprites and the debug values will point to them in place of the Metal Slug's ones. When it lands, if there is a sphere which is not touching the ground, it will change its colors to brighter ones. When jumping, the 3 spheres sprites will automatically align, while the Metal Slug sprite will return his normal palette and the 2 sphere sprites on the ends will change their color to black. In that case, the 3 sphere sprites will result misaligned and the Metal Slug sprite colors will become brighter, except the Vulcan.

This will also show 3 sprites under any Metal Slug and Girida-O's thread, which will determine the tank sprite rotation amount while walking on a vertical drop. The coordinates and their purpose are shown below. The coordinates remain until either one or both is on-screen, and will cease operations once it leaves the screen or is destroyed.

This dipswitch specializes in tank tread physics, displaying coordinates and graphical indicators to the Metal Slug and the Girida-O tanks.
