Xevious (NES)

A port of the much-loved arcade game Xevious. Namco handled this port themselves, and by all accounts it did very well indeed!

Debug Mode


At the title screen press and hold A or B on the second controller, then on the same controller press Right (x9), Up (x2), Left (x2), Down (x9). An 8-bit binary number will appear in the top-right corner of the screen. Press Left or Right on the second controller to highlight bits, and press A or B to switch them between 0 or 1. Press Reset to apply effects. Further resets will not disable any cheats.

Here's a table explaining the meaning of each bit, in order from left to right, and numbered from 0 to 7...

The US version contains the same cheat, but none of the bits have any in-game effects.
