Metal Slug rips still in tile-ripping progress

[c2000mc]

Please be patient. I'm still stressing my brain out with Tile-Viewer in order to get the whole thing. Found some cutoff pieces of the bus's stairs but keep in mind that it's very hard to align them with the right pieces. Now to show you what I;ve done so far:
Metal Slug 1
That Fucking Tank That dropped Stuff On You ICON
Metal Slug 2 (X){Please note that Aeshi Nero is not finished yet}
TOWEROFPOWER ICON
MOTHERF**KINGSNAKES ICON
Metal Slug 3{Same BG from last time just reposting it}
Mission5: MISSION5-2,5-3,5-4 ICON
Same thing once again
SAMETHINGDIFFERENTLINK DIFFERENT ICON
Metal Slug 4
NYAHAHAHAHA ICON

ps: Is there any free programs to make transparent GIFs and rotate images 1-360 degrees? I would like this help very much.
