I made these codes to be able to rip sprites from the game easily, though for some reason there is still one more layer I have yet to disable which is still overlaying a very fine light grey grid over the removed background elements that will have to be removed in your photo editor of choice. It may cause a tab bit of slowdown when enabled, but it's intended for sprite ripping only and not actual play. You can see some sprites I ripped (sorry if they suck!) for certain unused moves using this code here (I didn't rip the Orchid ones).

So I've been exploring this game for unused content recently, and found quite a bit of things along with some malicious stuff that should not have been released on the game's hard drive! If your interested in seeing what was found then go here.

Abystus, is it possible for you to find out if an Arcade game has a hidden code/cheat, just like how Mez is doing with the GBC games?

It's for the game Wolf Fang (Rohga Armor Force in the USA). The game has 4 endings, and at the "The End" screen for each, it shows you a piece of something that doesn't make any sense. Here they are combined: 1 PL, B 1+, B 3+, Start. (It really says: 1-PL, B-1+, B-3+, Start. But I removed the dashes so you don't get them confused with minus signs.)

That has to be a code and it only shows up in the Japanese version. But it could work on the USA version once someone finds out the actual code.

[Abystus]

If it is a code, the screen to enter it on needs to be found. Once found, it could be used as a compare for the US version (for things changing in memory allowing the code to be accepted). While it does appear to be a code, it could have been dummied out early on (unless you know it works somewhere in the game or has been reported to work online). I'll see what I can find when I get some free time tonight.

[ReyVGM]

I have never seen anyone mentioning anything about the game. I just thought that it looked like a code, so I'm asking around to see if anyone can find anything like Mez is doing with the GBC games. I doubt it was dummied out purely because they are letting you know about the buttons (or whatever) in an indirect way.

Alright, in the Japanese game use the code on the title screen (hold buttons 1+3 and press start on the player 1 side) after entering some credits. You will be brought to a mode select shown below:



I was not able to get this to work in the Rohga Armor Force game. I will try and look around for an enabler of some sorts if a modified cheat still exists.

[ReyVGM]

Holy crap, you rock!!

Out of all the combinations I tried it didn't occur to me that B meant Button.... I thought it meant something like pressing B or pressing Back. Of course, I completely forgot that Arcade games didn't have "B" butons... :P

No problem. I figured B meant button, but double checked the game input (press TAB in mame) to verify the 1, 2, 3 button layout. I've created a code to access this without the button code:

Wolf Fang -Kuhga 2001- (Japan) [MAME]

<cheat desc="Enable MODE SELECT">
    <comment>Enable before starting a new game.</comment>

    <script state="off">
      <action>maincpu.ow@001198=6608</action>
    </script>
</cheat>

I'll see if I can find it in the other game, but no promises as it may have been completely removed.

Edit:

The assembly code has been completely changed in Rohga, and it appears that my modifications are not allowing the screen to be shown. I'll take another look later, but from what I'm seeing so far it appears to be taken out.

[ReyVGM]

I'm just glad you found the code. I don't care if it's in Rohga. I'm asking in another forum to see if anyone can translate that what special mode menu means.

*edit*
Here is the translation:
"Play through all 12 stages consecutively with no regard to the story and go for a high score. Difficulty: Hard, no continues"

I guess that's the reason why the code is not in Rohga, in Rohga instead of having multiple paths branching in 4 endings, you just go through all 12 stages consecutively. So the cheat is kind of pointless... UNLESS the cheat enables the "normal mode" for the USA version :P

But I doubt it.

Mortal Kombat II (U) AR/GS [Sega Saturn]

Profile Modifier
16029BE0 E3??

00 - Kung Lao
01 - Liu Kang
02 - Cage
03 - Baraka
04 - Kitana
05 - Mileena
06 - Shang Tsung
07 - Rayden
08 - Sub-Zero
09 - Reptile
0A - Scorpion
0B - Jax

I find it funny that Kung Lao is listed first in the character roster, though he is the last to be displayed since the game automatically adds 1 to the base value for the first profile (Liu Kang). Pushing the game beyond its normal bounds just results in it being reset to Kung Lao unfortunately (I could try disabling the code that resets the value, but I think it would just lock the game tbh.)

Bloody Roar (U) AR/GS [PSX]

Hit Anywhere (Both Players. Excludes Throws.)
801505FE 2400
8015082A 2400

Eh, apparently this was already hacked by Thunder 2 (second code). Guess I need to get my eyes checked. The first code controls being able to hit ducking opponents with standard high attacks while being grounded (second code is for everything else, and does not hit ducking opponents by itself), so I will add the first code to his listing and give us both credit.

[Helder]

Awesome game that Bloody Roar. I played the shit out of that in the old days.
