Pic for clarity. The 2nd RNG call is on the top, it returns random value in v0 register. It returned v0=0x79 in this case, so that would drop the 1st item in FF4 (interval 0..0x80) but the 2nd item in Intelude/AY (0x77..0xC6 interval).

Alternatively, modify interval boundaries (also pictured). I suggest 0x66/B3/E6 = 40%/60% distribution for monsters which can drop 2 items, 40%/30%/30% (3 items), 40%/30%/20%/10% (4 items). Again, this will only happen if you pass the 5% roll first.
