| Hi, I’ve been searching this forum and the net for some info but havent fond the info i need.
I want to edit the graphics in super Mario kart. I know I need to use lunar decompress to access the compressed stuff but I must admit I don't quite understand how to use it... Another thing I want to edit is the character's name, which look even more complicated to do from my perspective. (I started to replace DK Jr. by Wario amongst other things) My offer is this: I'm willing to do sprites work or even 3d in exchange of some help. I know my way in tlp; I understand how to work with different color pallets and how sprites work. (I made lots of sprites for an rpgm2k project I had, same for an even older project using the hamster republic RPG maker (some shoddy editor which makes nes like RPG). I also know 3dsmax... So if someone is interested just send me an email or reply here, since I’m sure I’m not the only one that wants to do that. My web page if you want to see some of my stuff (it's under construction and this mostly traditional artwork) vpk.50webs.com Thank you p.s. I will post some image of my ongoing hack for smk later since I’m currently at work. (edited by vpk on 07-31-06 03:02 PM) |

| We have already found the answers to your questions, but will only post our notes once our hack has been released...
So I suggest you work on other things for now (graphics and stuff), which should keep you busy until we reveal the info you need... Good luck with your hack. |

| Oh, if you (or anyone reading this) ever figure out how to switch the driver bodies for the podium screen (as they all have different heights), that'd definitely help, and we would return the favor.
I already spent a bit of time trying to find those pointers, but with no success. I'll try more seriously later... |

| Hi there. It's been quite some time when I messed around with Mario Kart, but anyway, here comes an easy Introduction into using Lunar Compress for noobs XD
Ok. First thing you need is THIS TOOL. Assuming you work with windows (cause elsewise you'd know how to use Lunar Compress...), just download this program and install it to your machine. Having done this, open an explorer window and naviagte to the directory where both lunar compress AND a mariokart rom are located (just copy an untouched mariokart rom into the lc-dir). Having done that, right click onto the lc-dir and choose "Console Here". A new commandline window will pop up. Type into it (without quotation marks^^): "sniff.exe mariokart.smc 0 10000000 0 4 0" Hit return to start the program. It'll take a while and then the tool will have created a log-file which can be opened using a text-editor. There'll be some into inside like this one: Compressed Structure #123 Info... Start Address: 70200 End Address: 70CAC Compressed Size: AAC Uncompressed Size: 1000 Datastructures with a decompressed size like 1000 or 1600 or 2000 or dunno any even number similar may be a position of mariokart graphics. Actually offset 70200 is an example, where some of the graphics are stored. If you don't know where the graphics are stored, just try and decompress some of the suspicious locations. Now we'll run through the process of decompressing the given graphic. So just reuse the console-window in front of you and type "decomp.exe mariokart.smc graphic.bin 70200 4 0" and confirm with return. The program will create a graphicsfile in your lc-dir and you can open it using tlp. Modify it and stuff as desired and save it. Before reinserting it into your rom, you'll now have to check wheather the recompressed data is smaller or equal to the original because elsewise, inserting the new graphics would perhaps overwrite critical info (program code or something) that then makes the game crash randomly. So first, check the size of the recompressed graphic in typing: "recomp.exe graphic.bin delete.me 0 4 0" If the compressed size (displayed on the console) is less than the original one (here AAC(hex) == 2732(dec)), you can start inserting your graphics into the rom typing "recomp.exe graphic.bin mariokart.smc 70200 4 0". If everything went ok, your modifications now should be visible within the rom 
Any questions remaining? Just pose them! |

| Oh, and have a look at d4s' notes, wherever they are... The old URL doesn't work anymore, where is it now ?
And there's also this site: http://matt.yanos.com/smkpal/ |

| whoa, thanks a lot both of you, this is really helpful.
It's starting to make more sense in my brain now with some examples. and stifu, i must admit I have no idea how to change that too, sorry. (aussi, on a tu le droit d'écrire en français ici? héhé) |

Anyway, I've got 2 versions of d4s' notes on my comp, not sure which one is more recent, but here's one: http://stifu.free.fr/dl/temp/d4s_mariokart_info.txt |

| Here's some information on the text in Super Mario Kart including where the character names are stored:
http://rustedmagick.com/mb/thread.php?id=78 Stifu, how's Epic Racers coming? You guys completely figure out the AI and the Lakitu drop spots, right? That's going to be awesome. |

Originally posted by GlitchCog Those are only for the names shown in Time Trial. We also found the names shown on the GP result screen, and on the podium screen. Originally posted by GlitchCog We haven't figured out the AI or Lakitu's stuff, we're actually counting on Bouche's help on that, as he's thinking of working on TrackDes again... Epic Racers is coming along nicely, I recently finished drawing the 8th and last driver. We will show new screenshots soon, I think. (edited by Stifu on 08-02-06 03:02 PM) |
