Debug mode

The Debug mode can be activated using the aforementioned sound test number sequence, but there is an alternate way. When an attraction mode demo is playing, the player can press

on the second controller to toggle debug mode. So far, this is only proven to work on the European version of the game for the Mega CD and in the 920 prototype.

The controls for when debug mode is active are as follows:

• (Esc in the PC version): Toggles object placement mode.

• (Space in the PC version): Selects the next object.

• (Both versions): Places the selected object.
