So, if you shoot the right inner loop, nothing happens, but left inner loop works fine?
Impossible to Finish: Hoth MB (final shot), Tatooine MB, Endor MB, Endor III, Lightsaber Duel
Death Star II (?) will be much harder as you'll need to shoot Death Star three times. Death Star I,III,MB will be fine.
No Supers in Tie Fighter, no Video Mode
if you light hoth off the plunge you could play Hoth I video mode via another mode start shot. If you get the multiplier up high first that could still be worth good points, and depending on character selected it could light Hoth MB, which could be nice (especially if stacking MBs is enabled), even though you can't finish it to start victory MB.
R2D2 may still be a good option, but just avoid ever playing Endor III. Can still get to Death Star MB and possibly complete it for Victory MB.
