Crazy Taxi [SLUS-20202] - PS2

Constant RNG
2015B1E0 00601824
20175d28 00601824
20196668 00601824

This code causes calls to rand() to always return zero, resulting in some very interesting/wacky effects (try it!). There are 3 identical RNGs used by different parts of the engine, so this will affect all of them.

Wonder what other kinds of cool weirdness you could inflict on PS2 games? I like seeing other hackers with an eye for thinking outside the box. Welcome to the team!

1 - Lock camera in place
2 - Disable Command Menu
3 - Disable Health HUD
4 - Attack Mode1 (also enables bit 1)
5 - ?
6 - All character models and objects are invisible
13 - Same effect as bit 4?
14 - Same effect as bit 2?
15 -
16 - Same effect as bit 0?
17 - Squish camera, then control sora with floaty controlls. Can't interact with objects.
20 - Same effect as bit 2?
