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.
