Oh well. At least you put forth some effort. I think you should finish up your own work as well. I recall you being in the testing stages of your SMB3 hack - is this correct? Sorry if it's not.

I forgot to mention this in my last chapter of a post - and that is that entering a pipe in the special world-specific Bonus Area will take you back to the level you came from. The only way the special pipe won't take you to the special Bonus Area is if you play the main level in another world.

n that in a bit.

I chop up some unused level data sometimes to use secondary areas or bonus areas. You have to include a 9-byte level header in the number of extra bytes. Is this similar to unused enemy data? Usually I see 01 at the beginning of each enemy data offset; this must be some type of header. Any ideas? Should extra enemy data be handled the same way extra level data does?

---

Leave the FF that terminates the previous enemy data and replace the FF that follows with a 01. Enemy data doesn't require its own header. The header of the active level loads the enemy data through the appropriate code. The 01 is just there; however you want to put it. The last bit of enemy data terminates at 0xDA74. So you can make use of the free space from 0xDA75 onward. Just remember that the next bank begins at 0xE010, so you can only go as far as 0xE00F, if you even go that far. So I could put a 01 at 0xDA75, and then for whichever level is going to use that enemy data, point to 0xDA75 for the enemy data when loading it up for editing in SMB3 Workshop, or if adding the level to a pointer on your world map in the SMB3 Map Editor. It's pretty self-explanatory, so I don't want to continue rambling and building this wall of text concerning that.

As for the bonus areas... I looked it up out of interest to see where it could be changed in the ROM for whoever could make use of that data. Interestingly, a lot of the set offsets in SMB3 Workshop don't match the true offsets for the object data and enemy data. So here they are as they appear in the ROM (and loaded into RAM):

Underground Bonus Areas

Object Data: 0x3491B - 0x3492A (0x10) Enemy Data: 0x3492B - 0x3493A (0x10) Object Set: 0x3493B - 0x34942 (0x8) Object Data Enemy Data Object Set $A90B (0x3491B) $A91B (0x3492B) $A92B (0x3493B) ---------------------- ---------------------- ---------------------- AF B1 = 0x1B1BF 76 C9 = 0xC986 0E = Underground BC B1 = 0x1B1CC 78 C9 = 0xC988 0E = Underground 8B B2 = 0x1B29B 7D C9 = 0xC98D 0E = Underground 72 B3 = 0x1B382 88 C9 = 0xC998 0E = Underground D8 B3 = 0x1B3E8 90 C9 = 0xC9A0 0E = Underground 70 B4 = 0x1B480 98 C9 = 0xC9A8 0E = Underground E2 B5 = 0x1B5F2 A3 C9 = 0xC9B3 0E = Underground 5B B6 = 0x1B66B AB C9 = 0xC9BB 0E = Underground

Plains Bonus Areas

Object Data: 0x34B27 - 0x34B36 (0x10) Enemy Data: 0x34B37 - 0x34B46 (0x10) Object Set: 0x34B47 - 0x34B4E (0x8) Object Data Enemy Data Object Set $AB17 (0x34B27) $AB27 (0x34B37) $AB37 (0x34B47) ---------------------- ---------------------- ---------------------- 68 BD = 0x1FD78 60 C5 = 0xC570 01 = Plains 68 BD = 0x1FD78 60 C5 = 0xC570 01 = Plains 68 BD = 0x1FD78 60 C5 = 0xC570 01 = Plains B8 BD = 0x1FDC8 60 C5 = 0xC570 01 = Plains 68 BD = 0x1FD78 60 C5 = 0xC570 01 = Plains 68 BD = 0x1FD78 60 C5 = 0xC570 01 = Plains 68 BD = 0x1FD78 60 C5 = 0xC570 01 = Plains 68 BD = 0x1FD78 60 C5 = 0xC570 01 = Plains

1) Which levels have been completed in the current world in the current game. Obviously this information is held in RAM somewhere, because when you die or beat a level, you go back to the world map, and it still has a record of the levels you've beaten / mushroom houses you've visited / etc. I'm assuming the game doesn't hold all the world map data in RAM while simultaneously holding the current level data in RAM, right?

2) Which level I'm currently in. Obviously the level data is held in the ROM, and the active level data is held in the RAM. I've found the current world in RAM. I've found the current position in a given level held in the RAM. What I can't find is any kind of pointer or value in RAM that I could use to determine the current level. I just need to know where the value is stored, I can reverse engineer how given values relate to give levels myself.

3) The return coordinates for the world map. Like, I'm in a level, and I die. I am returned to the last completed level or the start of the world. Where are the coordinates stored in RAM so that the game knows where to return me to? Does the game store coordinates, or just a pointer to the last completed level in the ROM, which in turn is used to determine the coordinates?

---

Hopefully the following findings help. There is more data than the specific data you were asking/searching for, but I was planning to post it all anyway, so I'm throwing it all into one collective post.

$0022 - Level length $0023 - X-coordinate of column after far-right visible column on screen $0024 - X-coordinate of column before far-left visible column on screen $0075 - Map: Current Y-position (Mario) - Level: Current screen number $0076 - Map: Current Y-position (Luigi) $0079 - Map: Current X-position (Mario) $007A - Map: Current X-position (Luigi) $007B - Remaining pixels for Mario's movement (#$20 = 32 pixels) (counts down as Mario moves) $007C - Remaining pixels for Luigi's movement (#$20 = 32 pixels) (counts down as Luigi moves) $007D - Mario's last map movement 01 = Right 02 = Left 04 = Down 08 = Up $007E - Luigi's last map movement 01 = Right 02 = Left 04 = Down 08 = Up $00E9 - Current X-coordinate $00EE - Current character display (ex. 06 = Mario jumping; 4F = Mario jumping with fist in air) $7950 - Mario's moving speed on map (max = #$18 by holding directional pad down; FF = not moving) $7951 - Luigi's moving speed on map (max = #$18 by holding directional pad down; FF = not moving) $7976 - Y-position of current level entered (Mario) $7977 - Y-position of current level entered (Luigi) $797A - X-position of current level entered (Mario) $797B - X-position of current level entered (Luigi) $797E - Y-position for return point if Mario dies $797F - Y-position for return point if Luigi dies $7982 - X-position for return point if Mario dies $7983 - X-position for return point if Luigi dies $7D00 - $7D3F - Mario's cleared levels $7D40 - $7D7F - Luigi's cleared levels $7DD5 - Last map movement (applies to both Mario and Luigi) - Tells the game where the player came from to avoid them passing an incomplete level but allows them to go back - For example, you reach 1-2, moving from the left. The value is 01 (you moved right) - This tells the game that you moved from the left. You cannot pass the level in any other direction - You can modify this value yourself with a hex editor while viewing RAM - If we change it to 08, the game thinks we came from below (by moving up), thus we can move "back" down - Note: This differs from $7D/$7E. If you try to move in a direction that you cannot move in, these values still change $7DFE - $7DFF - Object data for next area (from level header) (ex. 1-1 Bonus: 93 BC = 0x1FCA3) $7E00 - $7E01 - Enemy data for next area (from level header) (ex. 1-1 Bonus: 06 C0 = 0xC016) $7EB9 - $7EBA - Object data for current active level (ex. 1-1: 82 BB = 0x1FB92) $7EBB - $7EBC - Enemy data for current active level (ex. 1-1: 27 C5 = 0xC537)

Additional notes:
-> $7976/$7977 + $797A/$797B are used to determine, if Mario/Luigi dies, from where they begin flying from.

-> $797E/$797F + $7982/$7983 are used to determine where they arrive after dying.

Here's a visual to help get an idea of how the data for the cleared levels per player is stored. Take note that for the bottom two rows, the game seems to determine which of the two rows the clear tile should appear on from the second-to-bottom row (seeing as how the only time the clear tile appears on the very bottom row is if the second-to-bottom row is not a level tile). Be sure to test different things out. I assume that the following rows for both Mario and Luigi apply to other map screens, but note that I did not test that theory out, so it'll be up to you to try that out.

I don't understand this part. If you leave the FF that ends the main bit of the enemy data, and change the FF that would end the extra enemy data, then the level would load other enemy data, right? I'm not so sure, obviously.

---

n as well. So if you refer to the images, the instructions finish on an incomplete note. Basically, all that's left to be said is what was actually touched upon in the previous post, being that once you have a new enemy set ready for editing, when loading up the level you're going to be editing in SMB3 Workshop, point to the appropriate offset for the enemy data. There won't be any enemies, but you don't have to worry about any original limit either because you're building on unused space! So add your enemies in, save, and I'd advise double-checking in a hex editor afterward to make sure that everything is how it should be, as well as to find where that new enemy data set ends and where the next one can begin. As I always mention, I also recommend keeping notes in a book or a Notepad text file of any and all custom offsets for object and/or enemy data that you use. And don't forget, when editing pointers in the SMB3 Map Editor, you can easily enter custom offsets as well, so there should be no problem in entering the proper custom offsets for object and/or enemy data.

How do you log data like the Map/Level data you posted last? I'm wondering where the offset is located for map animation types...

Do you mean which CHR-ROM banks are used to animate the tiles on the World Maps; or the code that determines which World Maps animate and which do not? If neither, could you please be a little more specific?

I've been making levels and stuff for the NES SMB3. All dungeons are edited. I have 10 extra bytes total out of all of them. How do I change unwanted "sky" levels into dungeons?

---

Interchangeable:
 - Sky & Ice
 - Piranha Plant, Giant & Cloudy
 - Water & Pipe

       1 - Plains: 0x1E509 - 0x2000F
     2 - Fortress: 0x2A7F7 - 0x2C00F
            *NOTE: 0x2A7F7 - 0x2A866 = 7 End Castles
        3 - Hilly: 0x20587 - 0x2200F
          4 - Sky: 0x227E0 - 0x2400F -----------------+
5 - Piranha Plant: 0x26A6F - 0x2800F -----+           |
        6 - Water: 0x24BA7 - 0x2600F -----+-----+     |
         8 - Pipe: 0x24BA7 - 0x2600F -----+-----+     |
       9 - Desert: 0x28F3F - 0x2A00F      |           |
         A - Ship: 0x2EC07 - 0x3000F      |           |
        B - Giant: 0x26A6F - 0x2800F -----+           |
          C - Ice: 0x227E0 - 0x2400F -----+-----------+
       D - Cloudy: 0x26A6F - 0x2800F -----+
  E - Underground: 0x1A587 - 0x1C00F

Free space (in respective order as the banks appear in the ROM, except for Underground
which I will present afterward):

           Enemies:  0xDA75 -  0xE00F (0x59B)
            Plains: 0x1FFD2 - 0x2000F  (0x3E)
             Hilly: 0x219FD - 0x2200F (0x613)
           Sky/Ice: 0x23FAA - 0x2400F  (0x66)
        Water/Pipe: 0x257A6 - 0x2600F (0x86A)
Plant/Giant/Cloudy: 0x27FEC - 0x2800F  (0x24)
            Desert: 0x29F54 - 0x2A00F  (0xBC)
          Fortress: 0x2BFF6 - 0x2C00F  (0x1A)
              Ship: 0x2FDE1 - 0x3000F (0x22F)

0x1BADD - 0x1BC3A (0x15E) - Unused space.
0x1BC3B - Shows bits of the end of 1-1 (Plains).
0x1BCA3 - 1-1 Bonus Area (Plains) duplicate!
0x1BCF9 - Seems to be the ending of something; maybe an early Water/Pipe beginning/end.
0x1BD43 - Attempted 3-8 Ending (Plains) from what I can tell.
0x1BD78 - Really seems to be just a mess.
0x1BDC8 - See previous. (Not sure if it's actually a starting offset for something or a part
          of the previous data set.)
0x1BDE8 - Attempted horizontal hilly-like level? (Again, not sure if it's really the start of
          something.)
0x1BE0B - Looks like 0x1BDE8 only with a light blue background.
0x1BE2F - Messed up early 3-3 (Plains)!
0x1BE58 - Another early 3-3!
0x1BE79 - Another early 3-3! (Wow; how many attempts did they need to take?!)
0x1BFAA - Attempted 3-3 ending by the looks of it.
0x1BFD2 - 0x1C00F  (0x3E) - Unused space.

nto something else. (Oh, and War in Hell, the Battle City hack that Googie previewed some time ago, was completed on my birthday almost 2 months ago, but I've been holding off on its release so that I can submit Luigi's Chronicles 2 and War in Hell to Romhacking.net together.)

I've used the free space in the Underground and Hilly banks, and I'm going to tackle the Water/Pipe bank next. I don't know how much space I'll actually get to use since I only have a few free bytes left for enemy data, but I definitely foresee it all working out proficiently. Then one more test run and it should be done! (Yeah, sorry about being over a year AFTER I originally predicted. Dang school. )

So I guess that's sort of an... open invitation, maybe? If I'm considerably worth that, that is. Despite the collaborative hack idea which was a failed attempt, I'd still be interested in possible future collaborative SMB3 projects, and considering how it seems SMB3 hacking is pretty dead again otherwise (unfortunately ) I'd like to possibly help to get thingymabobbers rolling again somehow or another... BUT I don't plan on doing anything like I had to go through with Luigi's Chronicles 2 ever again (i.e. doing a crap load of bloody crap all by my bloody self).

Out of curiosity, how are the SMB3 hacking projects for everyone else coming along? Obscure Kingdom (aside from Reuben being held off again due to an overseas shipment of some new mayonnaise)? Luigi's Quest? Mario's Trials? Googie's new SMB3 hacking attempt? Mario Adventure 3?!?!?! Well, anyway, hopefully things get rolling again.

As for the World Map animation-related code, I'll get to that later on if you don't mind. I already spent a while on this post and it's already long enough as it is, so next time. I edited it for Luigi's Chronicles 2, so it's not like I have to take time to search for it; it's just the matter of typing out an explanation for it and whatnot. As well, perhaps I'll post a little ASM-related surprise that can expand one's SMB3 hacking possibilities just a little bit in a way that actually reduces the length of the related code by a couple of bytes. Though yes, those things would best be posted as separate posts for referral purposes. So please post people so that I can post those thingies as well! Later, alligators. And remember - stay out of the water.

Also to note, there is unused space in a few of the ROM banks for the possible addition of more levels; some have more free space than others.

nly 26 extra bytes for the Fortresses. Maybe you could add your ten to it and get 36?
You could have more themes for your fortresses; like a sewer, or an icy place outside the fortress and save all the dungeon stuff for Boom-Boom. Does that good enough?

Also, world map animation code and/or explanation would be an excellent thing to have.

---

I definitely agree. This would allow for some good themes for each world.

I'm also curious how Mushroom Houses work, and how I'm going to implement Spade games.

---

Yeah, that list did leave out Object set F, Spade Bonuses, and Object set 7, Mushroom Houses. Maybe the level data for the Spade Bonuses are located near the other level data, but I'm not sure right now. I believe that the "Mario Bros." 2-Player minigame as well as the two others are pipe/water levels as well, and that those strange enemies in the very beginning of the enemy bank are used in those minigames. As for the Mushroom levels, the level data for a Mushroom House is at 0x24D70, and it lasts 90 bytes (5A in hex). I think there would be two or so more levels for the object set; one with one chest and the Princess's chamber. Right after the main Mushroom House comes 7-4.

Level structure for Toad Houses Bank 0: 08 - Treasure chest. 09 - Small treasure chest. 0A - Door that crashes the game when entered. 0C - Strange orange background for the level. A0-AF - Vertically layered house blocks. B0-BF - Horizontally layered house blocks - leaves a shadow underneath. C0-CF - Upper right shadow corner, extends down the right side when length is increased. Bank 3: 60-6F - Horizontally layered black background. 70-7F - Vertically layered black background.

Open invitation to what? Work on someone else's hack? You kept on saying that doing just about all of the work was like killing yourself, yet when I wanted to give you a hand, you rejected the offer. If you're going to do that when someone wants to help you out with your hack, then why should you think someone would let you work on theirs?
