Defense above 255 wraps around. The damage divide reads only the last 8 bits of the defense, so a defense of 300 counts as 44, and a defense of 256 counts as 0, which divides by zero and comes back as 65535.

Demons in the party hit half again as hard as the hero and the partner, but the result has to fit in 16 bits. A hit of 43691 or more wraps around to a small number.
The hit chance compares Ag + Lu/4 (In + Lu/4 for spells) of each side. When the attacker is ahead by 44 to 85, the table runs out and the game reads its own code as odds, so the attack misses 3 times in 4. Being a little ahead is much better than being far ahead.
27 items are never handed out: the cloaks Capa Mantle, Ageha Mantle, Phantom Mantle, and Baal's Mantle, Fallen Angel Wings, the Missile Launcher, and all 11 extra Shizudama among them.
The hero and the partner each have a sixth stat that never shows on the status screen. Body armour, masks, and cloaks raise it, and the hero's makes items sell for more. The story scenes meant to raise it by 1 hardly work: one check is written backwards, so the hero's only goes up once it is already 35 or more, and the partner's never does.
Every 16th time you beat an enemy while a demon of the same kind is in your party, the hero's and the partner's sixth stat drop by 1, but not below 5.
