Store the blaster's shot-effect history as EF_Effect*[6]. Both Fox/Falco and Kirby-copy spawn paths return EF_Effect*; storing those results as s32 truncates native pointers. Typed slots remove the narrowing casts and make the history's contents explicit.

Validation: all 1,133 compiled objects and the final DOL remain byte-identical to master. Focused ARM64 -O2 ASan/UBSan checks reproduce lost pointer identity in all four old variants and pass with the correction, including history rollover, null results, adjacent arrays and resets.
