Last view: 3220 days 		NOTE: ALL MEMORY/BITFLAG ADDRESSES IN THIS POST FOLLOW THE addr:bit FORMAT, E.G.

704A:3 WOULD MEAN MEMORY $704A, BIT 3 IN LAZY SHELL.


So, since there are 4,096 event scripts in Super Mario RPG, it would make sense that a decent list could be compiled, which might help with anyone looking to make their own hack. So, with that, here's a list of some useful events I've found so far that could be used by hack makers.

  • #4 This is the event that appears to kick everything off. It only does one thing though, and that's load Level 002, which is the one where mario chases bowser into his castle. I'd surmise the garden scene may be hardcoded.
  • #65 Event 65 causes the springboard animation, but does not seem to be set to any specific NPC. Also, if $7049:0 is set, instead of launching mario up, he will bounce off gently downwards (south)
  • #2496 Event 2496 is the event script that handles the scene where Mario chases Bowser into his castle at the start of the game. I haven't had a chance to go over it thoroughly.
  • #274 Event 274 is a generic shopkeeping routine. It takes input in the form of bitflag 7049:4 and memory 7024. It compares the number of coins mario has to the number in mem 7024. If mario has enough coins, it returns, with bitflag 7049:3 clear. If mario does not have enough coins, it returns bitflag 7049:3 set. As well, if 7049:4 is set, it will run dialogue 520, which by default is a "um, you're a little short" message. it does not alter your coin count, however.
  • #283 Event 283 is a generic 'give frog coin' event.
  • #286 Event 286 is a simple event called by other events that holds until Mario hits the jump button, for example in Mushroom Kingdom, the "look what you're stepping in" girl uses this in her events.
  • #279 Event 279 is coded to give mario a controllable number of coins, and play a sound for that. The number of coins given is controlled by mem 702A.


If anyone finds any events, or takes the time to dissect and document any, please post them in this thread and I'll try and edit them into this post.

The title demo is controlled entirely by event scripts

Here be the list

So, it appears that the title demo starts at event #128, and follows most events though normally. However, there are two points at which this order breaks- and in the file that's where the indenting suddenly resets. I'm not sure how event execution makes it from one set to the next, but I'm working on it.

  • #65 can be called to trigger the springboard animation. Not sure what this does for any other sprite, but with springboards, you should call it before doing whatever you actually want the board to do (warping somewhere).

#283 Event 284 is a generic 'give frog coin' event.


HOLD IT! Do you see the bold number (#284)? I think you should either:

Rename the 4 with a 3 on 284
OR
Rename the 3 with a 4 on 283

The save point in [0DC] (Smithy Factory, Area 2 w/save point) is the only save point not to use Event # 80. It also has a unique set of attributes as save points go. I don't know why this is.

It uses event #2390.

Discovered when looking for answers to a question that was asked on another board.

Last view: 4791 days 		If we are compiling a list, I would like to include it in the next release (V1.1) in a few weeks. Seems very helpful.

Also, has anyone figured out what determines the starting Intro event #? I would think it is hard-coded into the game. If so, we should figure out where its defined and Ill add it to V1.1.

Updated Title Demo Script Path


I do believe that will have the info you're looking for. Without knowing the UNKCMDs though, the script as a whole isn't quite contiguous.

#3827: "You got a (item)!" Sub-routine script. Store the value of the item (The number of the item) to Address 70A7 to make this work properly.

Use "Store value to mem (8-bit)" to make access to 70A7 avalaible.
You ALSO need to store a "You got an Item!" dailouge to 7000.

NOTE: ALL MEMORY/BITFLAG ADDRESSES IN THIS POST #4 This is the event that appears to kick everything off. It only does one thing though, and that's load Level 002, which is the one where mario chases bowser into his castle. I'd surmise the garden scene may be hardcoded.


Event 4 is actually useless. The Mario chasing Bowser event is hardcoded. I deleted this string and the chasing event is still intact.

The Garden scene is hardcoded, but it can be changed by shifting the ASM pointers. Careful with the ASM pointers though, it can crash the game.

Event 16-25 + subroutine 255 - Handles the battle scripts (they are ASM appointed so changing them will affect the auto-battle events unless you change the pointers.)

I have another question. What event controls the Booster Hill sequence the first time you go and how would I change it so Peach drops frog coins instead of flowers? Is that possible?

Last view: 4964 days 		Yes. Access the Level Editor and click on Fields tab. Under level properties, see what event script handles the stage.

Open Script Editor. Under events, find the number that the level uses. I think there is a memory assignment that handles it. If a certain memory has been set, it will run certain codes within the script, while ignoring the codes that run the first time events. The flower can be changed by removing the code that adds flowers, and replacing it with add x frog coin(s).

It may take time before you can get used to it. And oh.. beware of the Lazy Shell parsing error. It may corrupt some existing events.
