I'm tellin' ya, that's a great game. How hard could it be to make an editor?

Sure... give me a few decades to figure out how the game works

And another few to code

I'm going to have to ask that whoever makes this editor, for the love of pete, PUT PARTICLE EFFECTS IN THE GUI!!

That's a brilliant idea! I can't believe nobody has thought of doing it yet!

I mean, the actual technical details are none too hard.

Just have to unpack the files on the disk image, make a computer program that batch searches all the files for something that looks like the landing site (it has a distinctive shape, any of us could re-produce an accurate listing of its geometry off the top of our heads I'm sure, and the program would just translate the geometry into every known 3D format and search with them all. Nothing complex, probably just an hour of coding). Since the starting area is always the first area listed in the pointer table, (and no game has ever been released without a centralized pointer table to all of the areas in the game, because Nintendo passed a law about that through the International Japanese Parlament) we'd just have to use a similar search function to search every type of pointer known, and we'd already know where all the data was and their formats!

And then for the editor, we could do a ton of work with emulating the proper graphics drawing code and stuff, but I really think that's the past. The editors of the future will tie in with an emulator and follow all the data coming into the game, and let the user edit the geometry in RAM while playing the game, then trace the route the data took backwards and apply the change to the original image.

Now, the biggest problem we have here is that GameCube emulation sucks. So to get our hacks on, I think we should crack open our GCs and run the data line that goes from CD to chip through the computer -- a simple program could IPS patch all the data on the fly.

I'm way ahead of you, Squash Monster. Just now, I consulted a professional about what a pixel is, so we're not too far from the finished product.

You don't have it? Omigosh you're so dumb! Just type it into Google or something. EVERYONE has it.

I think I can Make an Editor, I just need to learn how to program (can someone do this part for me it seems hard), use hex (can someone do this part for me it seems hard), and find the data (can someone do this part for me it seems hard).

I'm afraid the level format is in raw HEX...

This is going to cause some problems...

After an hour of looking at the game, I've determined that the level format is nearly identical to that of Super Metroid. The only difference is that there is an extra byte to set Y position of each tile and BTS comes immediately after the tile property bytes (ie- 4 bytes per tile, instead of 3).

Graphics are going to be tricky, but levels will actually be quite simple.

Well, Nintendo likes to make use of its past games ; so guess what ? I found out that the dark & light worlds engine was taken from Zelda3; so, converting the SNES asm into NGC asm, we can surely copy the magic mirror routine to add an item in MP2 to change between both worlds anytime anywhere (actually I don't know if that is already possible in the game, I haven't finished it yet)
That's a nice step in hacking that game, isn't it?

I am currently programming a custom build of Dolwin 18321.32987 that add a whole planetload of debugging features. I currently am making astounding progress. I've alread programmed a tracer, model/texture exporter, and several other doohickeys that I have no clue on what they are. I even coded in the ability to automatically make a level editor for any game that it is running. In fact, I just made a private server for PSO. I even have finished coding it in the time I have typed this post.

You can get it here.

OMFG! He's posting ROMs! Well technically it's an ISO so I guess it's OK.

BTW I started working on the editor. I'm new to this sort of thing but I'm learning really fast... so far I can almost make a program that says Hello! I bet I'll have the editor finished tonight! Oh BTW does anyone know how to open files, read pointers, decompress data, render 3D, edit 3D coordinates, recompress data, and write to files?

(Seriously, though, I think he gets it. )

Dudes you fucking crack me up

As impressive as an editor like this would be I wouldnt really be that keen on it. Itd sorta be like editing Doom3 levels or making a half life multiplayer map. The hacking scene is based around retro consoles and should remain so. The N64 is previous generation and soon to be two generations old. Anyway hard enough to hack a snes game let alone a current gen Next we'll all be needing hacking development teams to do the work!

Breakthrough, guys. Turns out that Metroid Prime 2 was made using a computer. That will surely aid us in our conquest.

We also know the computer they used had a keyboard. That is crucial! I bet half the people that post here don't even have one! This could cause some problems for user compatibilities...
