Use this thread to discuss any of these modes. Here are a few resources to get you started:
1)
SIN moon's guide on Espgaluda II. Will include sections on BL, Arrange, and Omake! modes soon. Gives very detailed technical data on each stage, but is written entirely in Japanese.
2)
Shmups.com Espgaluda II guide by GaijinPunch. The best guide available in English right now, but it contains incorrect end game/clear bonus calculations (see below for the correct information).

The end game/clear bonus for the Arcade PCB (and Arcade and X360 modes in the port) is calculated as follows:
1) 20,000,000 points per life (max 120,000,000)
2) 10,000,000 points per life box (max 60,000,000)
3) 4,000 points per barrier division (there are 4,000 divisions in the barrier gauge, so the max bonus is 16,000,000 points if you end the game with a full barrier gauge)
4) Stage 6 clear bonus x2
So if you get all six life boxes, no miss the entire game, and end stage 6 with a full barrier, you can get 196 million as your clear bonus, plus the stage 6 clear bonus x2 (which is very little, maybe a million points max?).
As long as you get all six life boxes, you will finish your game with a minimum of 80 million points as a clear bonus.
