Unused Graphics

Since Atomiswave emulation isn't as versatile as Neo Geo emulation as of this writing, exploring the graphics data isn't as easy as it once. Best results seem to be from loading digging through the VRAM in save states of the PlayStation 2 port or Metal Slug Anthology on PSP.

This game has new characters, so you know what that means: needlessly converted animations!! Ralf and Clark get their own versions of unused animations from the previous games, seemingly using Metal Slug 5 as a basis on what animations were carried across. The throwing animation with the dual machine gun still cuts off like it did in that game, for instance.

Not all animations were converted for both characters; only Ralf gets to try out the aiming-backwards animations from MS1, while Clark hogs some aiming-upwards frames to himself. Credit goes to RandomRebelSoldier for ripping Clark's sprites.

This animation is used, but triggers very rarely: a Hunter Walker inverting itself from walking on the ground to the ceiling. The animation was later used in Metal Slug Defense and Attack. Cheers to Divison 六 for pointing this out to me, and RandomRebelSoldier for ripping it:

This wrecked missile is supposed to appear at the end of Mission 2 when the train boss crashes against the wall, but the missile always explode before then, leaving it unused. Ta Divison 六 for this.

The Flying Core in Mission 3 will fire junk as projectiles, resorting to shooting fish if you dodge it three times; these crabs were likely meant to be among them, but go unused. Cheers Divison 六 for ripping them and that factoid!
