Bankbank: Undo revision 21670 by Bankbank (talk)

stub page

* Bomb bonus
Bonuses are awarded for every bomb pickup once the player has reached 7 bombs (reaching 7 does nothing). Due to a bug, the actual stock also stops at 7 (it should correctly stop displaying at 9 and allow infinite stock, just like Mahou Daisakusen). Failing to pick up a bomb item clears the bonus index to 0, requiring a full restart of the bonus. Using a bomb or dying does not reset the bonus.

The bonuses are 1000, 2000, 4000, 8000, 16000, 32000, 655371. Due to a bug, the bonus index is incremented twice by accident, so you only see 1000, 4000, 16000, 655371.

Due to yet another bug, the bonus index is incorrectly capped at 6 (classical off-by-one due to confusing max bounds and array element count), exposing the beginning of a
different data table as the final bonus amount (leading to the last bonus being worth 655371)

== Fix info for bomb bonus bug as detailed above (ST-V version) ==

A) change 6015B7A shll2 to shll (in the file fpr19188.13, change offset 12B7A from 45 08 to 45 00)

B) change 6015b86 mov 0x06,r4 to mov 0x0a,r4 (in the file fpr19188.13, change offset 12B86 from E4 06 to E4 0A)

note that this only fixes scoring from the table. bonuses still begin at 7, stock still stops at 7.
