Official New Game Genie Code Thread

Nice, these work great already :) Yeah, the jumping is different from its sequel Rampage Edition. You take damage from jumping/falling from too much of a distance, sliding down (some?) slopes, etc. Also you die when falling too high a distance, before even hitting the ground :P That's probably what you meant by having problems.

Codes are fine the way they are, though I wonder if any exploration is possible by making Grant jump even higher. About landing without doing any damage, could this just be fixed by having already existing invincibility codes activated, or is health handled differently here? I am using 2 codes for invincibility, one of which refills health upon gaining damage.

The Raptor probably doesn't need jump higher codes. If you press/hold up and jump, its jump is already insanely high. You might break the game :P Hm, checking Gamehacking.org, it seems that I'm using USA codes. I guess USA codes also work on the PAL version? I'll have to double-check.

GelmiR, here's a super high jump code to test for exploring. Let me know if you need it any higher...

Jurassic Park (E)

0MRV-H97L
Jump much higher (standing still only). Can cause problems, so use with caution.

EDIT: I think a inf energy code or invincibility should stop Grant from taking damage when jumping too high.

Awesome, thanks :D Already broke the game trying to jump over the jeep at the start of the first level, lol. Would it be hard/possible to make walk on air and no clip codes? I don't really care about stability, it would only be for exploring. But I get that if it's hard to make these codes, it might not be worth it. Will do a full playthrough with the jump codes soon and get back to you. Haven't tested them on the raptor, by the way. Wonder if that would work. In Rampage Edition, you need seperate codes for Grant/Raptor. But I think in JP1 the invincibility codes work on both characters.

I also tried jumping over the Jeep and had the same outcome. Lol.

I had problems trying to make a walk on air code, but will try again and will also see about making a walk thru walls code.

Cool, thanks in advance :D By the way, I have to say that your work on Jurassic Park Rampage Edition (getting that early build to boot/run and the codes for the final version) is still some of my favorite work of yours :)

Thanks, I appreciate that. That was definitely one of the more exciting projects I've worked on.

I'm having trouble with the Walk On Air and No Clip codes for Jurassic Park. I've got one more idea I'm gonna try in a couple days. Fingers crossed.

You're welcome :)
Cool! Thanks for trying, no worries if it doesn't work out.

GelmiR, this game is fighting me all the way. lol. No luck on the Walk On Air or No Clip codes. I'll keep trying new code ideas in the next few days.

I assume you're aware of the built-in cheat that lets you use controller 2 to move your character freely around the screen? Do you have any interest in it? I might be able to make codes that modify that.

EDIT: Also, do you have the ability to turn codes on and off while playing the game? I've got some ideas if you're able to do that.

LinkueiBR, I've got the Game Genie codes you wanted for Prince of Persia 2. I only had time to do limited testing, so let me know if there are any problems.

There are two codes, one for each direction.

Prince of Persia 2 (Genesis/MD)


REWA-A6ZR +
REWA-A6YR
Prince will keep moving with sword drawn when holding Left or Right (instead of only moving one step).

Woah, you're fast!
I will test those codes more in my remastered mod, but looks like it works without problems!

"You must spread some Reputation around before giving it to Tony H again."

EDIT: Unfortunately this code conflicts when you turn around... Sometimes during the turn around move, the Prince will walk instead of simply look to the other side.

You can see the problem starting at 00:34s:
https://www.youtube.com/watch?v=WBkKZ0nddpc


I have an idea for another code request:

You can create a code to make the Prince always jump forward when pressed the Jump Button and only Jump up (to climb) when pressed UP button (Like the SNES Prince of Persia Jump system).

Thank you again for the amazing help that you can bringing to my project!

I figured out what's happening. If you quickly tap the button to make him turn around, he will just turn around. If you hold the button just slightly longer to make him turn around, he will turn around and walk forward a short distance. It's all about how quickly you tap the button. Now the question is, is there any way to fix that? I'll take a look at it when I get some time and get back to you. Will also take a look at the other request.

EDIT: When you say that you want to have the jump button make him jump forward, are you talking about like when you press the Jump button and the directional pad in that direction at the same time?

Yep (like in the SNES PoP1)!

No worries, Tony :) Thanks for trying! Yeah that map feature might be useful, I knew it was with the debug mode. Do I need controller 2 do to that? Asking because I haven't gotten a 2nd controller to work with my setup. And yes, I can turn individual codes on/off during gameplay at all times :)

GelmiR, I'll see if I can make it so that you can use controller 1 to move around the screen for exploring, and you can turn the codes off when you want to return to normal game play.

LinkueiBR, just spent quite a bit of time working on that PoP2 code to make the A button do an angled jump, but in the end I couldn't figure it out. Made some codes to make the A button do a few different things, but not an angled jump. Ugh.

Also, I don't think I can make those 2 codes I made earlier any better (the codes that make the Prince keep moving with the sword drawn). I'm pretty sure that if I was able to fix that, it would break a lot of other stuff in the game. I was kind of bummed out that those codes had that side effect, because they seemed to work pretty good with the sword drawn.

No problem Tony, thanks for your help!

Tony, thanks in advance for looking into map-mode codes for Jurassic Park :)

Think I finally got Jurassic Park figured out. Yay!

Might be best to use an invincibility code with these because you may still take damage when moving past enemies. It's kind of neat how this works, you can move freely thru any solid objects, but when you let go of the directional pad, you will drop down to the ground but not fall thru. Seems to work really well for exploring, or getting to hard to reach places.

Jurassic Park (E)

AJKA-AA2T +
AL4T-JA9T +
1YKA-ARB0 +
2NJT-ARE8
Allows free movement anywhere on the screen/map using controller 1. You can even move thru solid objects. Turn codes off to return to normal game play. This code uses the built-in password/cheat, but changes it so you can use controller 1 instead of controller 2.

Awesome, they work great! :D Will have some fun with this very soon :) Codes also work on the raptor. I've already found something nice in Grant's version of the visitor center (final level). At the far right of the first section of the level, is an area with some stairs, and an entry at the bottom and door at the top. The door at the top works, and will lead to the next section.
This area wit the stairs is normally not used/accessible as Grant. It's possible there were some powerups (as it's such a small segment) and they cut it for some reason. Or, as it is sort of used for the Raptor (though without the stairs), maybe it was never intended to be used for Grant.

Thanks Tony, will do more exploring soon :D

Edit: Codes are best turned on during gameplay. If you have them on from the beginning, they will mess with the menu options, password screen, etc. By the way (curiosity), what does each individual code do? Is it one for each direction, or am I thinking waaaay too simple here?

The first two codes turn on the cheat that enables free movement on controller 2, and the last two codes switch the RAM addresses for controller 1 and controller 2 so you can use controller 1 to move freely around the map.

Edit: Thanks for the heads up on turning the codes on after the game starts, will add that to the notes.

You're welcome, and thanks for the info! Will explore some more upcoming weekend and get back to you :)

Did some more exploring in Jurassic Park with map mode. Didn't find any real interesting things, but I did have a lot of fun with them. Definitely codes I will keep around, so thanks again for making them! :D I did break the game once when playing a Raptor level as Grant, and subsequently encountering Grant, lol... not even a soft-reset would fix it. But this was probably already possible with map mode with the 2nd controller :) The whole screen went a dark shade of red.

I seem to remember seeing that unusual dark red screen on a couple different occasions when I was making codes. Interesting. Was definitely not the usual blank/red screen you get when you need a master code.

Nope, it was much darker and you could also see some outlines :) Even resetting wouldn't work. In fact, reloading a save wouldn't work either. I couldn't move my character, and music was slowed down extremely. Good times, lol!

Edit: I think it happens when you move Grant over the Raptor's level version of Grant. I think they can be on the same screen, but them touching broke the space time continuum.

We'll just call it the STC screen. 😅

Deal :D Well, back to replaying Rampage Edition :)

Absolutely no useful codes for this game, so I made a few...

Super Battleship (Genesis)

For Super Battleship mode.

ABBT-NA9T
Enemies won't shoot at you or move during battle.

RF1A-R6YY
Sink ships with 1 hit. IMPORTANT: You can also be sunk with 1 hit, so probably best to use with the "Enemies won't shoot at you" code (ABBT-NA9T).

AJ1T-NA62
Infinite main gun ammo.

AJ2T-NA3J
Infinite missiles.

AJ5T-NA7N
Infinite torpedoes.

AXNT-BTBR
Light Cruisers start with twice as much ammo (24 shells and 4 missiles).

Nadia: The Secret of the Blue Water (w/English patch ver 1.1 by KingMike) (Genesis/MD)

These codes force the game to display English text when you're playing on a
Japanese console. Codes force English text everywhere I tested except in the
Sound Test menu (didn't think a separate code was necessary for that).

AKHB-CA2R +
AKJB-CA6R +
AKKB-CA7Y +
AKKV-CA20 +
ABRB-CA2R +
ABRB-CA4R +
AKLV-CA54
Forces the game to display English text when playing on a Japanese console.

Any chance of some Sega CD cheat codes since the Mega SD supports them?

Yes! Invincibility for Soul Star would make me very happy.

Does anyone know what type of codes the Mega SD supports? I've done some reading about it, but hard to find consistent answers. It sounds like it does support RAM type codes (that begin with "FF"), but I'm not sure if it supports ROM type codes. If it does support ROM codes, what format do they need to be in? Also, what format do the RAM codes need to be in? Maybe there's some kind of official document that has this info?

We have a ton of Sega CD codes/hacks at GameHacking dot org, but since there wasn't any kind of standard format for ROM type codes, we just stickied a couple of threads with all of the codes/hacks in them...

https://gamehacking.org/vb/forum/vid...a-cd-iso-hacks

https://gamehacking.org/vb/forum/vid...-hacks-patches

The site also has RAM codes for several Sega CD games (these will probably work with Mega SD): https://gamehacking.org/system/scd

I've made several Sega CD codes, but I think all of them have been assembly (ROM) type codes and not RAM type codes: https://codehut.gshi.org/SegaCDhacks.txt

Also wrote a guide on hacking Sonic CD: https://codehut.gshi.org/SonicCDhack.txt

The best answer I can give is this video frame of me entering a cheat code for Sonic CD. I think this is "always have 1 ring" or something like that. It worked, though the title screen was messed up. As you can see it's Game Genie-style on the left, and PAR (I guess???) on the right.

http://www.gamesack.net/crap/Segacdcheat.png

EDIT: I tried the codes for Batman Returns from Gamehacking.org. One set of codes were too long, having more digits for some reason. The other codes fit into the allotted space on the PAR (??) side, but did not work.

Joe, thanks for that screen shot, it helps a lot. If you don't mind, I'd like to have you test a few codes so I can figure out a couple things. I need to know if it supports ROM type codes, and I need to know which type of RAM code it uses.

The code you have listed above should set your number of rings to zero. If you set the value to something like 0003 (FF1513:0003), does it make it so that you always have 3 rings? If it does, that will tell me what type of RAM code it uses. If it doesn't, try this code and see if it gives you 3 rings: FF1512:0003.

For the ROM code testing, can you get the game/ROM: RDF - Global Conflict (USA)? If you can get it, try these codes and see if they work. I'll put them in Game Genie and raw format...

AD1T-CA5C = 1 hit kills enemies. (raw code= 01EF62:6000).

RHXT-C6TA = Infinite fuel. (raw code = 01E700:4E71).

If those codes work, that will be frickin awesome. From my limited understanding of how the Sega CD works, I think it uses something like the NES where there can be multiple "banks" used during the game, and it can switch between these while playing. Because of this, a single ROM type code may work in one section of the game, but not in another. If I remember correctly, RDF - Global Assault didn't seem to switch banks with those codes, so I'm hoping they will work. Let me know what happens.

P.S. Sonic CD switches banks a LOT, so ROM type codes for that game may be problematic.

EDIT: If those 2 ROM codes for RDF - Global Conflict don't work, try resetting the game with them active.

I have code ideas to improve Shadow of the Beast II, can you help me?

-The Mega Drive version has a weird border that cover almost half of the screen (WTF) they probably planned to put the HUD and text in this border... Can you make a code to simply disable this border?

-This version strangely dont change the background in the indoor areas except in the final battle... Can you make a code to at least complety disable Background B in the indoor areas? I could send you some save states to help to get in those areas.

-I searched in the ROM and like the AMIGA version, has mention to the "Ten Pints" code and even has "CHEAT MODE NOW ACTIVE" text, can you find and make code to active this mode?

EDIT:
-A code to make the game resolution h40 (320x224) instead of the h32 (256x224).

Thanks Tony!!!

LinkueiBR, will take a look at that when I get some time. Some of that sounds interesting.

This is the best I can do for now. This code shows the actual "Cheat Mode Now Active" text (along with other text), but I couldn't figure out how to actually activate the cheat, and I'm not even sure if it's possible. However, I read somewhere that the way the cheat works on the Amiga game was that if your health gets to zero, it just refills and you don't die. I've done exactly that with the code below. Your health refills when it reaches zero, and you will eventually become invincible (you can walk thru enemies and enemy fire without "touching" them). Again, this is probably not the real built-in cheat mode, but should be pretty close.

Shadow of the Beast II (Genesis/MD)

DCPT-4PRC +
A3YA-NA8N
Start a new game and walk Right until you get close to the first enemy and the text window opens. The text window will say "CHEAT MODE NOW ACTIVE" (with lots of other text). When your health reaches zero, it will refill and you will eventually become invincible.

EDIT: Doubtful that I'll be able to figure out the other requests in your post.

This makes it so I always have 3 rings.

This makes it so I always have 768 rings.

Unfortunately the codes for RDF Global Conflict did not work even when I reset. :(

Joe, away on vacation, but will work on some Sega CD codes when I get back. Thanks for the info.
