  • Need help with a code for Double Dragon (Genesis)

    I stumbled on a PAR code for Double Dragon purely by accident. I found a code that modifies the order that some of the enemies come out.

    This will modify certain enemies in place of others. I was wondering if there was a way to find other enemy modifiers. I've tried using addresses close to the one listed below, but haven't had any luck. Its hard to do a search with the PAR2 because everyone appears in the same place & in the same order. That being the case, the values don't change.

    If there is one that could be found for Game Genie, I might be able to get it converted.

    I'm not ready to add this code to the database yet:
    FF0E07: 000?

    Note: At the start, the man at the top closest to Williams (carrying Marion) will be different. Sometimes, you'll see Jimmy Lee, a second Williams, a second Marion, or a second Shadow Boss (in red). or Most of these values will show Jimmy Lee stuck at the start of Mission 2 (on the fence) & one of the enemies are missing. If you move to where Jimmy Lee is off the screen, the enemy will appear. When Linda appears in Mission 1, she'll have the bat. When she swings the bat she turns into Billy Lee & turns back to Linda. You may experience a brief stoppage at times. Abobo & Shadow Boss aren't supposed to wield knives. This typically causes the game to reset.

    Values:
    0 - Jimmy Lee appears in Mission 1 (can beat on him) - Stuck at start of Mission 2; you can leave him behind; Don't know if you can control him or not.
    1 - Jimmy Lee appears in Mission 1 (stuck in one spot) - Stuck on Mission 3 when Jimmy Lee walks by
    2 - Makes Billy & Jimmy Lee enemies (probably a variation of the Mission 2 enemy boss)
    3 - Linda appears where the guy with a bat in Mission 1 appears; the 2nd stage enemy boss appears (she's wearing green); Appears in Mission 3 just past the door, before the forest section (wearing red); Also appears in Mission 3 after you climb up to the enemy base.
    4 - Abobo appears in place of the guy with the bat in Mission 1; Appears in Mission 2 where Linda normally comes out; Appears in Mission 3 where the one of the guy jumps out of the trees; The game resets shortly after that.
    5 - Williams appears in place of the Mission 2 enemy boss (wearing Green); Didn't seem to notice much else with this code.
    6 - Rowper appears in Mission 1 in place of the guy who normally has the bat; Appears in place of the Mission 2 enemy boss (with a greenish tinge); Appears in Mission 3 just before the forest section.
    7 - Shadow Boss (guy with the machine gun) appears in Mission 1 in place of the guy with the bat; appears in Mission 2 in place of Linda; appears in Mission 3 in place of one of the guys in the trees; The game resets shortly after that.

    Code:
    All Enemies Are Lindas
    SWLA-BCN0
    ARLA-AAE2
    ACLA-AAE4
    
    All Enemies Are Adobos
    SWLA-BCN0
    AWLA-AAE2
    ACLA-AAE4
    
    All Enemies Are Williams
    SWLA-BCN0
    A0LA-AAE2
    ACLA-AAE4
    
    All Enemies Are Rowpers
    SWLA-BCN0
    A4LA-AAE2
    ACLA-AAE4
    I didn't go through the whole game so I don't know if they will crash. The Shadow Boss crashes the game. It looks like the enemy ID's start at FF0A47, You should probably get the other enemy ID slots by adding 0x40 everytime.

        Sorry about sending everyone the PMs. I got a little bit excited when I first found it. I did some heavy duty messing around with the game & I believe that I have found all of the PAR codes related to this. Here they are:

        Enemy modifiers
        FF0A47: 000?
        FF0B87: 000?
        FF0CC7: 000?
        FF0E07: 000?
        FF0F47: 000?
        FF1087: 000?
        FF11C7: 000?
        FF1307: 000?
        FF1447: 000?
        FF1587: 000?

        I found a couple of unrelated codes that affected enemies & noticed that the addresses were similar. I managed to locate my hexadecimal calculator & started adding & subtracting & managed to test these codes. Just for fun, I set the value at 7, which is for the Shadow Boss (or Mr. X). The I had three of them on the screen at once shooting at me on Mission 1. Cool stuff. In any case, I'll add these to the database. Thanks for your help guys.

        Also: I found that the difference between addresses is 140 (HEX).

          I was wondering if it might be possible to change the color of the enemies too. I got to thinking. Since there's about 3 different colored Lee Brothers & Lindas & 2 different colored Abobos, Williams, Rowpers, & Shadow Bosses, would it be possible to modify their appearance? Say maybe always have the Green-skinned Abobo or Linda is always dressed in Red w/ brown hair?

            I think it is possible to do that but it will be tedious. just like my streets of rage 2 palette hacking (1 palette conssists of 31 par codes).
