Now, paste all of that in the options area. After that, click "add cheat".

Then, double-click your new cheat. The list should appear.

Double-click the place you want to use co-op in, then tick the cheat's box.

Now, exit off of cheats and go to multiplayer.

Tell it you want two players.

Do a single game,

Go to Targitzan's Temple Shootout,

Then press enter. (Start)

And there you go! Your on co-op!

YOU SHOULD BE NOTIFIED:

The L button will take you to where you have the cheat set. If you use this during co-op gameplay, some of the graphics might be disrupted temporarily.

If you leave an area, the game will switch back to single-player.

Only first player can trigger cutscenes.

During cutscenes, it only plays on 1st player's screen, but slightly overlaps 2nd player's.

Second player can move around during most cutscenes.

If a player dies, the game ends like in normal 2 player mode.

Using any other cheat at the same time as this one may result badly.

Thanks!
