Here's some new snes game genie codes.

Contra 3
**C9-6D6F stage select. Use DF-D1

Super Ghouls N Ghosts
C9BB-A460 very few zombies appear
DF65-DFA8 most zombies carry a basket
CBBD-AF9F+
**BD-AFBF+ stage select. Use DD-D6. Turn code off after
FCBD-AF2F the stage loads.

Final Fight 3
**D3-7D0F stage select.
DBD7-5F0F start with 9 lives player 1
DBD9-54AF start with 9 lives player 2

For Final Fight 3, I have a request. There is a debug screen when you pause the game with alot of neat options. I've tried without success to activate it and would really like to see this code made. It can be par or game genie.

Debug Mode Available(Enable this code, then reset the game. On the Capcom screen, hold 'Select' on controller 2 until the Debug Mode comes up, or use the 'Always Get Debug Screen' code with this one)
7FEC-EDD7

Always Get Debug Screen(Use this with the 'Debug Mode Available' code, and you won't need to press any buttons to get to the Debug Mode menu)
3CDC-E46F

I remember hearing about that FF3 Debug. There was a button access code to use it in the European version. But I didn't know whether or not it was still in the US version. It's pretty cool that US players with the game can use it now.

PS - Your codes have been added Hackwiz.

Thanks for the quick reply Ugetab! If you don't mind explaining, how and what do you look for when you're trying to find this type of code.

For this code, I found the debug text in SNES9X ROM addresses, then decompiled from the start address to the text address, copied it to a word processor, and looked for things that accessed that area, with a 00FFF0 mask, using the line that the text actual started on, and deducing from there.

Once I found the line that accessed the text, I back-tracked from there, finding jumps to that routine through trial and error, and by using a similar mask to find all 4 digit jumps to areas close to where I thought the routine started, which led to somewhere near the start of program execution. I used Step Over to trace what was happening where, and to find where the hang-up in the code was. In this case, I think they nulled out the first digit in the compilation date, and used a check to see if that digit in the string was null. There appears to be some test-mode strings in the earlier Final Fight games, but I haven't found a way to activate them at this point.

Thanks for the info, I'm still amazed at how fast you found that code. I'll attempt using that method on the next game. Will that also work for the NES and the Sega Genesis?

As for the Final Fight games, I don't know if you seen these codes and I'm not sure who created them.

Final Fight 1
D4BD-DD01 pause the game to enter test mode

RGB menu-pause game and push select. Hold L button and press left or right to increase or decrease the background width. Hold Rbutton and press left or right to increase and decrease RGB values. Hold R button and press up or down to change pages.

Hex Editor-pause game and press the X button
Instant Reset-hold start and press select

EDC0-A4DB debug option. Press A button on controller 2 to fire bullets. I think you can only shoot the bullets while you're facing to the left

7EFFFA01 debug mode

The basic method applies when attempting this on Genesis or NES, but modifications are needed. NES has bankswitching and 4 byte jump addresses. This means you'll be using a decompiler, then trying to find the right area in currently banked ROM with FCEUXDSP, and hoping you can get there from the starting point. On the plus side, you won't need to worry about SEPs and REPs messing with how the code is decompiled.

Genesis is probably going to be quite a bit harder though. I tried getting to the Debug text shown in 'Terminator', but didn't make any headway at all. With no breakpoints to tell if the text is being read from some line, you'd be forced to either find a line that appears to read that text, or find some of the cheat options and backtrack in code from the addresses that write to those areas. I'd say that the area select is the best way to try doing that, at this point, as lives could be fickle to the hacker in this game.

I guess since I'm just learning how to do this, I'll start with what appears to be the easier of the 3, the SNES, and go from there.

Here are a couple of par codes I was able to find so far this game.

Final Fight Guy
7EFFFA01- debug mode. Works the same as Final Fight 1, but a couple of additions that I'm not sure is on Final Fight 1. At the intro story, push select on controller 1 to pause the intro story and push X or Y button for a hex editor. You can also do the same thing on the title screen.

7EFFFCFF- at the Capcom logo, hold select on controller 2 till the character screen comes up. Choose Guy or Haggar with the A or B button and it will start you off in a demo room fighting one of each enemy from the game. Also if you push select on controller one to stop the "push start" from flashing, you can play thru more of the game.

Somebody else already found that debug code. But that is the first I heard of that Test battle thingy. It sounds intriguing. I have added it to the site.

Sorry about posting that then, I didn't realize somebody found that code for Final Fight Guy. Here's the game genie version of that code: 6E6D-046D

From the looks of it Final Fight and Final Fight Guy codes are interchangable. Probably the only thing that was changed was Codys graphics and edited a few of his attributes. So every code is compatible basically.

This has been added to the site.

Here's some more game genie codes for Castlevania 4

CB26-DFAF
**26-D4DF stage select. Start game with code on, when the game
DD26-D40F starts you on stage 1, turn code off and die to start on the
6926-D46F level you want

CBAA-6DAF
**AA-6FDF start with and always keep weapon. Use DF-D9
69AA-6F6F

CBA3-6DAF this gives you a triple shot even if you don't have a weapon.
D4A3-6FDF Don't use if you pick up the watch. Also, you can omit the 1st
69A3-6F6F line of this code if you use the start with and always keep weapon code

Here are a couple of par codes found on Gens for the Sega Genesis

Contra Hard Corps
FFFA48:0*00 stage select. Use 1-C. Turn code off after the stage loads

FFFA48:0001 Debug level (for text only?).
You start off in a level where you proceed to the right(climbing, jumping, etc) but half way thru it dead ends. There appears to be two ways to go, but the screen dead ends. The only feature I was able to find was that by shooting, you can go thru all the text in the game including the ending. Maybe somebody can figure out more.
