Enter R-Mode using any door. Crystal Flash (away from the Power Bomb blocks!) or farm the upper section enemies, except for one. Tight 1-screen shortcharge between the bottom doors. Both shells need to be opened. If R-Mode is entered below the Power Bomb blocks, you'll need to use a clip to get to the upper section without destroying the barrier.
