| I was looking at a few things in the newbie FAQ about sprites, namely the responses to these: Q) How do you edit how sprites works? / How do you add new sprites? A) You can't... Yet... Q) But I saw a hack where some of the enemies was changed! A) Don't look! Don't ask! Forget all about it. It never happened. OK? The answers state matter of factly that you just can't edit how sprites work. What exactly does this mean? Wouldn't it be more appropriate to just say it requires ASM or changing data tables in the ROM? By modifying one byte, you can change whether an enemy can be killed with a cape or fireballs. You can change the tiles they use (not the exgfx, but rather tile mapping). You can change the area that will cause interaction with a sprite (essentially it's size). With ASM you can give code to the unused sprites that must be inserted manually in LM (sprite 12 for example). I'm pretty new to the board, so I don't know if this stuff has been done before, but I've found it entirely possible to do some stuff with sprites that the FAQ may cause you to think otherwise. I'll try to whip something simple up to show a bit of what I'm talking about. |

I dont know if exactly what you said is possible, but many many people hvae told me that editing the sprites through the 16x16 editor is impossible. I have found this to be wrong tho. I can change there palettes, and what they look like and simply save it by pressing shift + F9 (or ctrl + F9). It works fine, just I can't change what they do... BMF/Neko did a hack with a chuck boss that he edited and made that boss have HP or something like that. |

| First of all, this should have been posted in the newbie questions thread. Q) How do you edit how sprites works? / How do you add new sprites? A) You can't... Yet... Well, of course you can edit and add sprites. You can make the game do anything (exept for breaking SNES's limits) by ASM and such. What I meant was that there is no KNOWN way to add/edit sprites, with a few exeptions. Q) But I saw a hack where some of the enemies was changed! A) Don't look! Don't ask! Forget all about it. It never happened. OK? I wrote this to prevent "OMG!!1 i SAW THAT HAKK BY KT. i DUNNO WHAT IT WAS CLLED BUTT IT HDA DOSE DIAGONAL BULLT BILLS!!!1 DAT MEENS EDITIN SPRITES IS POSSIBL AND DEREFORE, CNA SOMEONE PLZ AD KARRIBUS SHOO FROM SBM3!!!1? KTHX" questions.  |

| I've thrown together a one level demo that features a classic stompable goomba. I think what makes this different from what other people have done in the past is that I did not replace an enemy in order to add it. My goomba is it's own sprite (number 12) that can be added manually in LM using Crtl+Ins while in sprite adding mode. Right now it's tiles are mapped to use the SMW goombas, but I think I may look into using the Nintendo Presents tiles instead. The ROM is not locked, so download it and take a look around if you're interested. I can post the data I've used to do this, if there is interest. Next up, I'm going to try to make a SMB1 style hammer brother. goomba_demo.ips These goombas are stompable  |

| Wow, impressive! Besides the fact that they explode instaid of flatten(you didn't have the beta SMW flatened goomba sprites most likely anyway, and it's just an example)that's awsome! Is it possible you could show how you did that? What ASM code you made and what it means in english, how you set it to use sprite 12, and how(or if)you used the Lunar Magic RATS tag format to protect it from being overwritten, or maybe you could just say how you learned this yourself. | |||

Just a hint: you've said about use Ctrl+Insert right? There's a easier way. Just open "add sprites window", click in which sprite you want with mouse's left button and with the right botton in level editor. Your sprite will appears. When you change the sprite, first click in any place from LV to choose another one, otherwise you'll place the same sprite that you have already used. So the only way to edit sprites is via hex editor? (edited by Mario Maniac on 08-26-04 05:23 PM) |

Sweet...new sprites BTW, dont use the Nintendo Presents graphics. Fusoya told people that the Nintendo Presents thing is used to keep track of mario and yoshis size/movements or something like that. So did modify that. Its used for mario and/or yoshi. |

| It's where Mario's and Yoshi's graphics are actively updated into so he can have more sprites without limiting the space for other sprites or BG items if it is possible to read from that area. | |||

| Someguy: It may be surprising, but there isn't a whole lot of ASM in this demo I made. I was going to release it with none at all, but there were a few things that I wanted to improve. The two things I did end up doing with ASM were preventing the goombas from entering shells and making them explode when stepped on (I only did the second one because I didn't have a sprite designed for the smashed ones). As for a RATS tag, I've only gotten into hex/ASM in the past two weeks, so I wasn't really sure what one was or how to use it. I just made an assumption from what I saw in the ROM to just prefix my custom code with 53 54 41 52 and end it with FF, but I don't know for sure if that's all there is to it. Even though I didn't write much for this demo, without ASM I never could have traced through the code to find the necessary sprite data. The first important thing I found was a subroutine starting at SNES address $07F7A0 that runs when a sprite is initialized. It loads data from 6 major tables in the ROM. Listed below are the ROM addresses for the begining of the tables and the RAM locations they are associated with. 0x03F46C -> 7E1656 0x03F535 -> 7E1662 0x03F5FE -> 7E166E 0x03F6C7 -> 7E167A 0x03F790 -> 7E1686 0x03F859 -> 7E190F All of these tables are indexed by sprite number (starting with x00 for the shelless green koopa). Here's a few of my notes about some table values. I've still barely touched the surface of all this data. I have the RAM locations as the headers, cuz that's what I see in my trace logs. 7E1656 setting both bits 5 and 6 makes an enemy stompable setting bit 8 changes the cape/star kill style 7E166E setting bit 1 changes the gfx page bits 2-4 tell which palette (8-F) the sprite uses setting bit 5 disables fireball killing of the enemy setting bit 6 disables cape killing of the enemy 7E1686 if bit 8 is set the sprite passes through floor bit 7 is set if the enemy is sprite creating (which is created is in a different table) 7E1662 I've noticed that changing data here changes the area for sprite interaction. For example, you've probably seen in hacks where rexes have been changed into goombas, you can still get killed by an invisible rex head. Fixing this is as simple as changing rex's table value 0x03F5E0 (0x03F535 + AB) to x00. Keep in mind that not all sprites use the data loaded from these tables. Some get new data from their own tables found in sprite specific routines. For my demo, I just changed entry 12 to match entry 00 for all six tables. I then needed to make sprite 12 use the code for shelless koopas, so doing some tracing I found another very important table at ROM address 0x0087CC. This table holds the memory locations (2 bytes for each sprite) to go to for the handling of each sprite. Sprite 12 intially jumped to a RTS command (made sense since it's listed as a null sprite), changing it to use the shelless koopa's code finally gave me some results I could see. I had a sprite that acted like a koopa, but the graphics it used was off. 7E1602 holds the animation frame, but I needed to change the tiles that the frames used... more tracing, more tables. 0x009E7F is the begining of an offset table that is indexed by sprite number. 0x009D83 is the start of a gfx tile table that is indexed by a value in the offset table. For example the entry for a green shelless in the offset table is x09, so the gfx tiles for the shelless start at 0x9D8C (0x009D83 + x09). Again not all of the enemies are stored here. I started to document which were but lost interest. I'll include what I did find though: (0) 82 A0 - koopa Walk 1 82 A2 - koopa walk 2 84 A4 - koopa turning 8C - koopa shell 8A - koopa shell ani 1 8E - koopa shell ani 2 (9) C8 - shelless walk 1 CA - shelless walk 2 CA - shelless turn CE - unused?

(4B) 80 - spiny walking 1 82 - spiny walking 2 80 - spiny turning (4E) 84 - spiny egg 8x8 tile 1 frame 1 84 - spiny egg 8x8 tile 2 frame 1 84 - spiny egg 8x8 tile 3 frame 1 84 - spiny egg 8x8 tile 4 frame 1 94 - spiny egg 8x8 tile 1 frame 2 94 - spiny egg 8x8 tile 2 frame 2 94 - spiny egg 8x8 tile 3 frame 2 94 - spiny egg 8x8 tile 4 frame 2 For my demo, I gave sprite 12 the same offset as the SMW goomba, and that's precisely what appears. The more I look through the ROM, the more tables I see, so hopefully this will spark some interest in documenting them. Right now I'm working on making a SMB1 style hammer brother. So far I've got the code for hammer throwing (almost a direct copy of the SMW's hammer bro) and have a modified rex calling that code. I still have to rework to code for his movement, but hopefully I'll have some more to share in the not so distant future Well that does it for me... after about an hour of typing this post I'm sleepy |

| This.. Is... (Somewhat) Utterly.. GROUNDBREAKING! (Or so i think.) Woohoo, great job, mikeyk. Quite seriously... This may be the revolution that we need.. To make original hacks.. (Of course, the people that know ASM) And a RATS Tag is like so: (Copied from a post that BMF Made in my Free Locations thread before the board went poof) But, yeah, if you're reserving space after the first 512K, just make your own RAT tag like so (shamelessly ripped from LunarDLL.h): S T A R ssssssss SSSSSSSS cccccccc CCCCCCCC (8 bytes) "STAR" Tag identifier, which is the word "RATS" reversed in all-caps. SSSSSSSS ssssssss Size-1 of data, 16 bit, little endian. It does not include the size of the RAT tag itself. CCCCCCCC cccccccc Inverse of size-1, 16 bit, little endian. Min/Max size allowed: 1-0x10000 Have fun, and keep up the good work mikeyk! |

| This is truly amazing!! I really need to start reading into ASM... In a few levels in KT's hack he has respawning sprites...which I really would like to have. Hes got, mecha-koopas, platforms, goombas, and my favourite...torpedo teds! The torpedos is what I really need, but some respawing wigglers, doubled stemed Pirana plants, or bullet shooters that fire out bombs like in SMB3 would be AMAZING!!! Good job with finding this! Now all we need is some music editing...  EDIT: I was looking at sprite 12 in LM (unedited) and it was only 1 16x16 tile. Now, what if I wanted to make a large hammer bro (SMB3 Giant land) which looks to me like it is 4 16x16 tiles. How would this work? Would I have to find an unused tile that is 4 16x16 tiles or what?

Originally posted by Kario... What? Why? Oh, and Keikonium, after a great deal of speculation I've come to the conclusion that he merely used bullet bill launchers placed on top of custom blocks that change sprites touching it in to (insert sprite here). I believe this is so based on some of the activity of diagonal bullet bills in certain levels (bouncing off of launchers and going in the same direction as they would have had they been launched from it, mainly). If I'm wrong, feel free to correct me, anyone. |
