various rips

[Barack Obama]

Added:
- Main Menu (DKC, SNES)
- Slug (Dual Orb, SNES)
- Forest Battle BG (Dual Orb, SNES)
I saw that the first Dual Orb wasn't on TSR so I did some quick rips for it. More game progress is impossible since there is no translation.

Also the jungle bg for Donkey Kong Country has an extensive palette change in level 1 so I'm not doing it.
Maybe this is how the modified bsnes+ emulator by Random Talking Bush could be useful, since it shows the VRAM changes in realtime. And since the modified variant shows raw colours like vSNES, I will probably give it a shot at one point.
Fast palette changes are more conventient to rip like this than with vSNES (each palette change requires one ZSNES quicksave to view it).

Anyway, I'm done with DKC and I will now continue to finish playing through Dual Orb II so I can decide what to rip from it.
