Duplicate Casino Geometry Data

If you enter and exit the Casino area, copies of the casino geometry will appear at their global location, providing proof that the adventure fields were originally meant to be built as one piece, but then segmented for efficiency (the SA engine had a hard time rendering things before it got the DX upgrade). The texturing is glitchy, as anything rendered by the SA engine is when it has erroneous texture refrences. It will frequently revert between textures, and sometimes even animate them.

Station Square Hotel Keys

flarn2006 found that, by using the Action Replay to enter the hotel early as Big, keys similar to the Wind Key or Ice Key will be found by the door. When placed in their appropriate sockets, the door will unlock.
