Efficient, safe pow using EXP opcode

I recently stumbled across ds-math’s rpow() being a O(lg n) safe implementation of exponentiation. Such a function is ultimately created because the EVM EXP opcode is unsafe wrt. overflows.

Why are there literally no Super Princess Peach DS ROM Hacks? [closed]

This is one of the crazier scenarios at least to me, since given Super Princess Peach is such an off-the-wall and unique game, complete with crazy mechanics and design ROM Hackers could work with, not to mention Princess Peach is emphasized AND the main character, in her own game, you’d think ROM Hackers would flood […]
