Minor glitches
Powie AI glitch
In the final version, Powie never jumps more than two times before doing a ground pound. This behavior is carried over from Mega Man Battle Network 2, where it is actually caused by a glitch. However, this game introduces a new AI glitch: it's actually supposed to attack after one jump 20% of the time, but it only does so under extremely rare circumstances.
This glitch is caused by the way the game determines whether Powie should attack after its first jump. The game does this by generating a random number r and using the SDK function for division, which calculates both division and modulo result. However, the game then uses the division result (r / 5) which has 429496729 possible values, instead of the modulo result (r % 5) which has 5 possible values.
