OK...
brought more unused stuff from RoB, only problem was that most of them i needed to rip it with yy-chr tile viewer because mednafen's debugger only lets me see what's in memory, so basically no palettes, only grayscale for now.

interesting things i found where:
1)jumping kid
2)briefcase
3)tiny stage title, candles and recovery items
4)stage boss announcement(only for death)
and 5)what seems to be subweapon icons similar to maria's, only the turtle is the same(left her subweapon icons for comparison).
that's all folks.
