Super Smash Bros. Melee Action Replay codes

I only have codes for the US version 1.0 and 1.2 of Super Smash Bros. Melee, because those are the versions I own. I do not know how to convert them to other versions. Use the links below to switch which version you need.

The Codes

Dual 1v1 Mode:

In my normal Smash group of 4 players, we have limited time and no one wants to wait out matches, yet we prefer 1v1-style fights. This code allows this by letting all 4 players play at once, but each "set" of 1v1 players can't directly interfere with the other fight (beyond things like messing with the camera or edge hogging). Once each pair has a winner, the two winners can battle it out for the overall winner of the match!

The only downside is that you can no longer play team matches with Friendly Fire turned off - but no one worth their salt plays Teams without Friendly Fire turned on anyway. Also, a side effect is that most stage hazards will no longer affect players - there is information in the hacking section below on how to fix this if you really want stage hazards to still work.

To use:

  1. Turn Friendly Fire to OFF.
  2. Switch to Team mode and set the team colors so that each set of players that should fight each other are the same color. Players will only be able to hurt other players set to the same team color.
  3. (Optional) Switch Team mode back off so players can switch to whatever costume they want.
  4. Start the match
  5. When the match is over, re-shuffle team colors as desired (this step can be skipped using another code further down!).

Shuffle teams based on rank:

The Dual 1v1 mode is pretty cool, but having to switch teams around after every match can be tedious. This code gets rid of that step by automating the shuffling of team assignments based on the rankings from the previous match. With it, there is no need to switch to Teams mode at all, unless you just want to check as a reminder of who is fighting whom.

The players that recieved 1st or 2nd place will be set to fight each other for the next match, and the players that got 3rd and 4th place will fight each other. When the game is first booted everyone can fight everyone, so you can treat the first match as a FFA "placements" match that determines the pairings for the first paired-off match.

Of course, even with this code enabled, you can still at any time manually switch to Teams mode and change around the pairings before starting the next match.

Note: In the unlikely event of a tie, this code will not compensate and will still assign directly based on rank. You will want to manually go into Teams mode and fix the color assignments in this case.

Disable some stage features:

Many stages have annoying features that interfere with a straight skill-based fight. Argue fairness as you will, but we would rather not have stages do some of this stuff. This code disables the following stage features:

  • Brinstar: Rising lava
  • Corneria: Attacking ships and Great Fox gun
  • Dreamland 64: Wind
  • Fountain of Dreams: Moving platforms
  • Green Greens: Wind, apples, and falling blocks
  • Peach's Castle: Switches and Bullet Bills
  • Pokemon Stadium: Transformations
  • Yoshi's Story: Shy guys

Stage hacking tips:

Smash Melee's code keeps a linked list of objects with update functions, which it runs through and calls the update functions every game frame. This list is constantly having objects added to and deleted from it. Each stage adds several objects to the list, and the easiest way to change the stage's behaviour is to tell these functions to not do anything.

Each stage has an initialization function, and while it is possible to find out what function is run for each stage by following a series of several links in memory, the easist way is to put a breakpoint at the address 0x801BFA90, start the stage you want to mess with, and then step once when the breakpoint is hit. This will put you at the start of that stage's initialization function.

During the initialization function several objects will be added to the update list. To find where the update functions are, starting from the initialization function you found, scroll down the code to find the return code (blr) and put a breakpoint there. Next, put a breakpoint at the address 0x8038DF40. This is part of the function that adds new objects to the list.

Now let the code run until that breakpoint is reached. When it is, look at the address in register #28. This is the address of the update function for the object being added. Keep running the code and jot down the addresses in register 28 until you hit the breakpoint at the end of the stage's initialization function. After that, more objects will be added all the time but they are not related to the stage.

There are two global update functions you will see that should be ignored - 0x801C0D00 (which updates animations) and 0x801C0D68 (unknown purpose). The rest are likely specific to that stage. Many of those will be nothing more than a return (blr) though, as an "empty" update, so those can also be ignored.

A quick change just to see what happens is to take those update functions and tell them to just return immediately by using a code like 04XXXXXX 4E800020, where XXXXXX is the last 6 digits of the address of the update function. If that does more than you intended, you may need to step through the update functions and find things to change, often just telling it to skip a branch or something using 60000000.

You can also try to mess with the stage's init function, though I've rarely found this useful. One thing that has been useful to know though is that many objects have init functions of their own, where additional steps are taken. For example, I had to edit the init function for the main stage platform of Green Green's in order to get rid of the initial yellow blocks. You can find these in a similar way to finding the update functions - while in the stage's init function, put a breakpoint at 0x802122F8 and step once to get into the init function of initialized objects for that stage.

Good luck hacking!
