The Jungle Book (Genesis)

RF5B-26TL +
AF5B-2AA8
Pause the game and press B to enable the debug menu. The debugger contains: Map view, inf energy, inf lives, inf time, palette editor, level select, an option to keep you from falling thru openings to your death (Solid Floor), etc.


Enabling the debugger in The Jungle Book was very complicated. You had to be in a certain spot in the game, jump off a cliff, then as you were falling, you had to pause the game and enter 19 button presses.

My prayers are answered, I'll have to check this out later. Love the game but Mickey controls like a sack of potatoes.

Sack of potatoes, lol. Hope it works out for you.

The starting and stopping multiple times is most useful while you're in the middle of a game with lots of shit going on around you.

[Tony H]

Another way to do it would be this: 0EF2:6006

This causes it to branch right to the debugger routine. This was the first one I made, but the problem with it is that you press Start to pause the game, and when you press Start again to unpause, it goes right to the debugger. I realized I needed one button press (C) so that the pause feature could still be used.

[terpsfan101]

Thanks. I never thought about starting and stopping the tracer multiple times before.

After starting and stopping it a few times, I started it again, and entered the controller cheat. And you were right, the log started where the controller cheat was located.

And changing 000EEC:720F to 000EEC:7200 makes sense now after you explained it.

[Tony H]

Well, I still can't figure out how you found it. The only lead we had for the Hellfire Debug Menu was a button counter at RAM address FFFFD8, which happens to be the button counter address for Zero Wing.

This one wasn't too bad because the cheat is entered while the game is paused, which means there is very little going on. You would pause the game, then start the Gens Tracer asm log, then stop and start it a few times to make a definite "break" in the log, and then (with the asm log running) enter the controller cheat, then stop the asm log. With any luck, the very beginning of the controller cheat asm will be right after the "break" that you made. Here is what it looks like...

Where it says TRACE STOPPED is our "break".

The instruction at 00:0EEC (the instruction I changed to make the debugger code) is putting a value of #$0F into register D1. This determines how many button presses it will compare (a little further down) before it runs the debugger routine. I changed it to 00 which means only one button press needed to run the debugger routine.
The instruction at 00:0EEE moves the value from controller 1 to register D0.
The instruction at 00:0EF0 compares the value from register A1 (which is the ROM address for the controller input values for the cheat) to the value in register D0 (which is the controller value).
The next instruction is a conditional branch (Branch if Not Equal).
The instruction at 00:0EF6 tells the game how many times to jump back to the beginning of our little compare routine (at 00:0EEE) before moving on to the next instruction (the debugger routine). The number of times it jumps back is determined by the value in register D1 which we changed with the Game Genie code.
