    I fixed the crashing error by changing the code.

    The fact that it doesn't respond to input unless it's running with IDA seems to be entirely separate.

    On a slightly off topic note. If anyone manages to get an exporter working for the character models, do post them please, regardless of the low poly count.

    Thirded (sp?). I've always wanted the Sonic R/S3DSaturnSS/Jam/protoSA1 models sooooo bad, because there the only models I've ever seen in all of history that captured the charm of classic Sonic 100% no matter how blocky they look. Give the models and I'll love you forever plzkthx~ <3

    Thanks?

    All I really did with this game is some redundant research, posted something from a YouTube video, and wrote two little programs.
     
  7. It WOULD be pretty cool if this Sonic R hacking could actually enable some sort of adventure game, not racing. That'd probably be really difficult, though. :P
     
  8. Hmm, this looks interesting. I've seen SMK being hacked, but this seems cooler as it is in 3D. Can't wait to see more hacking pictures!

    I've always wanted to see the Sonic R engine used for an actual Sonic game. Maybe one of these adventurous hackers could use the newly released Sonic Xtreme textures and stuff... ;)

    Hey saxman, if you read this, could you explain the .ter files a bit more? The info you gave me isn't very understandable.

    Unlike my previous editors, this one pulls the graphics from the proper files instead of having png files with it. You can also 'paint' in this one, rather than clicking 50 times. Requires .NET Framework 2.5 or greater.

    And, as proof that it works:
    [​IMG]<!--QuoteEnd--></div><!--QuoteEEnd-->
    Heh. I actually made a floor editor like that about three or four years ago, written in VB6. It even read in the graphics the same way. The biggest difference was that you had a palette of tiles on the right rather than using a spinbox, and a menu bar for selecting the MAP/PLY files and saving.
     
  12. Any more improvements on the Map Editor?

    Well, now it seems like Sonic R doesn't want to respond to inputs even when I run it from IDA. And I still can't get it to run in a window.
    It looks like I won't be doing much with this unless someone can figure out how to fix the control problem.

    EDIT: okay, looks like IDA 5.5 is not working. It still works with 5.1.

    Anyway, in case I haven't already said these, the RAM addresses I have found so far are:
    Code (Text):
    1. 008FB8EC&nbsp;&nbsp;&nbsp;&nbsp;4 Bytes&nbsp;&nbsp;&nbsp;&nbsp;Course
    2. 008FD50C&nbsp;&nbsp;&nbsp;&nbsp;4 Bytes&nbsp;&nbsp;&nbsp;&nbsp;Rings P1
    3. 008FD538&nbsp;&nbsp;&nbsp;&nbsp;4 Bytes&nbsp;&nbsp;&nbsp;&nbsp;Speed P1
    4. 008FD588&nbsp;&nbsp;&nbsp;&nbsp;4 Bytes&nbsp;&nbsp;&nbsp;&nbsp;Distance from ground P1
    5. 008FD5E6&nbsp;&nbsp;&nbsp;&nbsp;4 Bytes&nbsp;&nbsp;&nbsp;&nbsp;Character P1
    6. 008FD6D4&nbsp;&nbsp;&nbsp;&nbsp;4 Bytes&nbsp;&nbsp;&nbsp;&nbsp;Character model P1

    It looks like DXWnd wasn't working because I had Windows 95 compatibility mode set for Sonic R. And, Sonic R responds to input if I'm using DXWnd, even without IDA.

    They left a lot of debug strings in this game, which is quite helpful for figuring out what the game is doing. Here, have some functions:

    Also, looking at InitIsland etc., it would seem that 94BCF4 is the current weather setting, as it loads the snow data if this is equal to 2.
    The code that skips the Network menu when moving right on the main menu is at 488938 in RAM, and the code that adds to your ring count when you collect a ring is at 49676E in RAM.
     
  17. So apparently Super Mario 64 level editing has just become a lot easier. Some guy released a program that can port levels into Super Mario 64 in .obj format, and it does it pretty well too, apparently:

    <a href="http://www.youtube.com/watch?v=t-PtJIFz2tI" target="_blank">Spiral Mountain in Super Mario 64</a>
    <a href="http://www.youtube.com/watch?v=-Dmsc7mKOLE&feature=related" target="_blank">Rusty Bucket Bay in Super Mario 64</a>
    <a href="http://www.youtube.com/watch?v=OX1wWNnaZB4&feature=related" target="_blank">Level made with Google sketch-up in Super Mario 64</a>
    <a href="http://www.youtube.com/watch?v=gKcpfHhrBUg&feature=related" target="_blank">Some stage from Aidyn Chronicles in Super Mario 64</a>

    There's a lot more all over Youtube, too. But what I'm wondering is if the Sonic R tracks models could possibly be ported over to this .obj format and then ported into Super Mario 64? (If the models have been ported yet, I don't know if they have, but I'm assuming so)

    Over half of that post has little to do with Sonic R...

    Anyway, sure they could! If we knew the format. Which we don't.

    Hey there, I joined this forum because of this thread. :)

    I think I read through everything so far, but let me get a few quick questions out since I haven't had any sleep yet and I have class soon. Please forgive me if I ask any ignorant questions (and kindly point me to a doc/link)

    When I go to look for the UV's or 3D vertices for the models, what byte sizes should I expect for the verts and the UV's? I quickly read the SA model format to get an idea of what to expect in general, it shows 2 shorts for each U and V, and a Float[3] for each vertex, but since Saturn's an older machine I'm assuming much more frugal setups, or perhaps strange byte orientation? (I recall one machine even reads its disc backwards?)

    Also, which .bin file would be the smallest and probably best to try and analyze? And do you think this engine even uses weights? It looks like it may be just static meshes attached to a skeleton, as I can see mesh clipping when I play the game, so currently I'm guessing that all those tiny .bin files in the character directories are probably just body parts.

    I'm an artist but I wanted to cut my teeth on some binary stuff, so I'm just starting my learning path on packed data. Please bear with me ^^; Any advice or pointers would be greatly appreciated.

    I can say the games models should not be using weights at all, it is using a hierarchy system like SA1 for animations. For the verts it's been a long time since I was messing with them, and I can't seem to find any notes I wrote down so I don't know how the verts were set up. I think they were just 3 floats X/Y/Z.



    If you want to try with Sonic's model it would be BIN\OBJECTS\SONIC\SONIC_H.BIN. The other .bin files in the directory are animation files. The .grd files from what I remember is lighting data for the characters, but I might be wrong on that part, it's been a long time since I messed with the game.
