Eh no, the thing we "discussed" was wether the SM64 text is a 3d model or a text*. In short: Replacing text is easy, replacing models is not
Even with the comming model importer you still would have to extract the SM64 Logo model from the ROM and edit it with Blender (or some other 3d modeller). But as the model importer is not ready yet, you'd even have to replace the model data manually with a hex editor and I guess that would be a /bit/ too complicate.
As I said though, it may be easier to replace the model with a square that is textured with an alternative logo (could still be quite hard to do though).

*The thing about the SM64 logo in levels was just the "proof" that it's a model.

Furthermore, when Mario would change direction (from "right" to "left" as seen in SMB) the camera would end up showing the other side of the level (mirrored) and Mario still going right.

To make a 2.5d level, the camera would need to stay perpendicular to the level, not to Mario. I guess that we're getting closer to find more details on how the lakitu cam works, and that we could eventually program such a camera setting, but for now it doesn't seem like a simple hack can achieve this.



Sorry to reply late to this but have been to busy to post.


I think, that there is probably a way you can make it the way it should be. I think that you can make object dissapearance in a way so that, there is the camera, a block and then mario and another block. That way he cannot deviate from the straight path. Then just find a way to make the objects dissapear like they do depending on the distance from the camera. I'll try to make a diagram of what I mean when I can.

From an Over head view, so if your above looking down. y

Like this mario cannot walk out, and then make those 2 lines (which would be immovable blocks I guess) not visible to the person playing. Very complicated and I will try to make a better diagram when I can.

Even if there was a block to stop him from deviating from the path, if the player walks up the camera will still go into that direction because Mario still changes direction even if something is blocking his path.

When i try to change the "1996 Nintendo" in the first screen, but also "PRESS START" in the second screen, after use a tool to recalculate CRC, it only shows a black screen instead of the first one; after it runs normally. What can i do?

Try changing one at a time first. Maybe you made an error in changing one of them.

Yes i tried just now; and so, using CHKSUM64.EXE to correct the CRC, it does nothing now (the emulator complains as i did not recalculate it). But i'm sure i did it well. Why me? -.-

This is an interesting thing I found while working on my hack.
Turns out that the levels that do not have act selections copy there acts from the previous level.

Castle grounds in the list of bytes after 0xE8D98 has the byte 00.
I tested this with other non act selecter levels such as Peaches slide as well which has a byte of 13.

by making one level with an act selecter warp to a level without it, if that level were on act 1, the objects I had on act 1 in the other level would appear.

So the same would go for act 2.

I tested it, and it did the same thing with the byte 13.

Here is a video demenstrating this find. (Note: The levels look like the same level but are different. I had to use multiple levels to fix a camera glitch for the underground.)

While trying to solve a bug in "The Missing Stars" (Goomba on the roof in the first area) I found the trajectories of MIPS the Rabbit. There's a table for its trajectories at offset 0x79068 of the Inside Castle 0x07 bank.

Here's the code that loads this base address. Easiest solution will be to move it to extended memory so MIPS can work on all levels:

802F85FC: LUI A0, 0x0708
802F8600: JAL 0x80277F50 ; segmented_to_virtual function
802F8604: ADDIU A0, A0, 0x9068 ; I hate you signed addition

Here's the table: (0xE84B6F in ROM)

0x07078EF8
0x07078F2C
0x07078F68
0x07078F7C
0x07078FA8
0x07078FD4
0x07078FE8
0x07079004
0x07079020
0x07079044

Each of these entries points to a different trajetory. Seems like they are somehow combined to form MIPS movement (though one would have to plot them all in the Inside Castle level (basement area) to confirm this).

Time: One second ago - Date: Tomorrow - Weather: Sunshine - Mood: Moody Answer to the universe: Yes
Our good friend yoshiman (aka yoshielectron), the super SM64 RAM hacker, stumbled on the table that determines the content of "!" boxes.

You can check out his video where he tells us where in RAM the table is located in the different versions, and shows us some cool things to do with it.
<object width="425" height="344"><embed src="http://www.youtube.com/v/QkgwHezZk54&hl=en&fs=1&" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="425" height="344"></embed></object>

Of course, being a ROM hacker, what interests me is where the table is in the ROM. Turns out it's in the checksum protected area at 0x0EBBA0.

Here's the table content:

 
00 00 00 87 13 00 3D B8 -- Wing Cap

01 00 00 86 13 00 3D D8 -- Metal Cap

02 00 00 88 13 00 3E 1C -- Vanish Cap

03 00 00 BE 13 00 1F 3C -- Koopa Shell

04 00 00 74 13 00 09 A4 -- One Coin

05 00 00 00 13 00 09 64 -- Three Coins

06 00 00 00 13 00 09 84 -- Ten Coins

07 00 00 D4 13 00 3F DC -- 1up Mushroom Static

08 00 00 7A 13 00 07 F8 -- Star 0

09 00 00 D4 13 00 40 10 -- 1up Mushroom Runs Away

0A 00 01 7A 13 00 07 F8 -- Star 1

0B 00 02 7A 13 00 07 F8 -- Star 2

0C 00 03 7A 13 00 07 F8 -- Star 3

0D 00 04 7A 13 00 07 F8 -- Star 4

0E 00 05 7A 13 00 07 F8 -- Star 5


The first byte is the byte used by the second behavior parameter of the "!" box itself. Bytes 2-3 are behavior parameters you want to pass to the object being spawned by the box (for example, byte 3 determines the star number for the star objects). Byte 4 is the model ID, and the last 4 bytes are the behavior pointer.

If you put TT64 in hexadecimal mode you'll be able to find values for the model ID and behavior pointer that are suitable to spawn any object you want, as long as it's available in the level you plan to put the box in. (note: in TT64 0.5.x the first byte of the behavior pointer i.e. 0x13 is omitted).

Of course, as with other stuff in the checksum area, if you change something there you'll have to either:
-Disable the checksum (look in this thread to see how).
-Recalculate the checksum.
-Use an emulator that doesn't mind if the checksum fails.

Now if we were to relocate this table where we have more space, we could probably have up to 256 different kind of items available for "!" boxes.

The memory address of the table is loaded by the 2 instructions at 0x0x0007C8E0 (ROM).

I've tried to change it's location, but the emulator hangs after I break the box, and when I look at the memory in Nemu64, it looks like it didn't load the part of the ROM where I put the table.

With this hack, you can easily set a region of the ROM to be loaded in extended memory hack. Just changing the pointer loaded in register A0 will work. When copying the table, remember that the last empty entry, indexed 0x63, is also part of it. If you remove it, any invalid value (not part of the table) for the box content will make the game stuck on an infinite loop.

The table can be expanded as much as you want, however you'll have to keep 0x63 as the last entry. This doesn't mean you can't use higher values than 0x63, this is what I mean:

[..]
62 00 04 7A 13 00 07 F8 -- Star 4
64 00 05 7A 13 00 07 F8 -- Star 5
65 00 05 7A 13 00 07 F8 -- Star 5
63 00 00 00 00 00 00 00 -- Last entry, empty box

That's because instead of multiplying the table index by the size of an entry lenght, the function uses an while loop to match the number to its content, so they don't have to be sequential.

Also, something important to keep in mind is that:

LUI A0, 0x8033
ADDIU A0, A0, 0x8BA0

is different from

LUI A0, 0x8033
ORI A0, A0, 0x8BA0

because of the signed addition. In the first case, A0 will be 0x80328BA0 while in the second case it will be 0x80338BA0. Not that this happens in this specific table case since the number being added is less than 0x8000, but it's always to good to be alert when pointers are loaded using LUI + ADDIU instead of LUI + ORI.

I did manage to load the table in an unused but loaded part of the ROM shortly after my post.

About the ADDIU instruction, I had this problem (I'm very new to MIPS assembly, but fortunately it isn't very hard to learn since I'm already decent with x86 assembly). Also fortunately, ADDIU and ORI take the same parameters, so just changing the opcode works.

About the "Extended Memory support", it looks very interesting. I'll have to look at it

Also, what debugger/disassembler do you use? I use Nemu64 and IDA Pro, but Nemu64 can't load "extended" ROMs.

Haven't used any disassembler in a while, I mostly use an giant .txt file with the entire checksum-area disassembly dumped from Nemu and step-in through the code using the same emulator. When working on "The Missing Stars" hack I ocasionally used Project 64 1.4 debugger, but it isn't very practical compared to Nemu's.

You can run the extended ROM on Nemu if you use this modified version of Cellar Dweller's "alternate" extender. The normal extended ROM doesn't run because some data isn't aligned and Nemu seems to be the only emulator accurate enough to make an issue out of this. Toad's Tool 64 seems to run this 'aligned' ROM fine.

Lakitu's data:

RAM 0x8032ED50 -- 0xE9D50 in ROM
RAM 0x8032EE08 -- 0xE9E08 in ROM

First table seems to be coordinates (index + 3 16-bit signed integers)

Second table seems to deal with rotation and camera speed, but I haven't experimented a lot.

Ask that question in the quite clearly marked SM64 Help Thread, not here. It's irrelevant and distracting when posted in the middle of a bunch of data finds.

Tidy found 304 warnings and 4 errors!

The alt attribute should be used to give a short description
of an image; longer descriptions should be given with the
longdesc attribute which takes a URL linked to the description.
These measures are needed for people using non-graphical browsers.

For further advice on how to make your pages accessible
see http://www.w3.org/WAI/GL.
You are recommended to use CSS to specify the font and
properties such as its size and color. This will reduce
the size of HTML files and make them easier to maintain
compared with using <FONT> elements.

You are recommended to use CSS to control line wrapping.
Use "white-space: nowrap" to inhibit wrapping in place
of inserting <NOBR>...</NOBR> into the markup.
