Time Slip

A Contra-style action game with time travel elements.

Debug Code#

At any point during normal gameplay, input the following code: L, R, Down, B, L, R. The screen should quickly fade twice to signify that the code has been entered correctly. This toggles the following:

• Bullet Level is always at 4.
• The player always has 8 lives.
• Pressing the R Button on the 2P controller will skip to the next area of the level.

Manual Reset#

This is enabled by default. Pressing the L + R buttons together on the 2P controller while in the game proper will reset the game. However, due to the way this is coded, the game will freeze after the opening credits screen.

Removed Map Editor#

Text for a complex map editor is present in the ROM starting at 0x424CE, but it does not seem to be present in the game anymore.
