NEW TUTORIAL HERE:

--------------------
Tarek701 is dead.
Updated! Old Assembly tutorial trashed and wrote the new one from scratch. I extend it currently.

you obviously haven't even wrote a single asm code. because if you'd write an asm code and use the instructions like this, you would realize, that everything, that you didn't copy+pasted from google, is completly wrong.

correct use (and i tried to explain you this, but you are seemingly a bit stubborn...):

Code
LUI T0, $8033       #T0 :=80330000
LW T0, $ddf4 (T0)   #T0 :=the content of 8033DDF4


If you want to load a value into something, do it like this:
Code
ADDIU A0, R0, $0005  #A0 := 5
OR
ORI A0, R0, $0005 #A0 := 5


guess, i'll make a passable tutorial soon, i'm scared, that you are continuing this.


stop making such dumb tutorials, that are completly wrong and give people wrong informations.

There is a little difference between SPIM and SM64(There is a difference in syntax. It's sad, that you didn't know that). Please get your facts right. I've used LW as it is used for SPIM. I also explained, that we don't use LW and SW, as it is NOT for SM64. This tutorial (the basics first) are simply just teaching the opcodes and not how to assemble them into game. This is something, which comes in Lesson 2 first.

Also, if you want to complain, go here:
Department of Computer Science
University of Maryland
A.V. Williams Building
College Park, MD 20742
Web: www.cs.umd.edu
Phone: (301) 405-2662
Fax: (301) 405-6707

That's the department of computer science, the people who helped me and many others with the MIPS assembly tutorial, that's also the people, where I got the register documentary from. I'm sure you will get to hear a nice: "Yes, we gave him permission to use the 2003 documentary about MIPS"
The restly code is written completly by me.

okay, sorry, i though you wanted to make a tutorial about MIPS R4300i. Guess, i shouldn't have read the title of the topic, stupid me :V
(sarcasm, obviously)

also, verrify your shit; in SPIM your LW is wrong, too.
(quoting the website, you've send:
lw Loads a word from a location in memory to a register. Address in memory must be word-aligned
so don't put this university into shame.)

Damn me, I didn't know, that you lack on a very important part of information. Assembler Tutorial and Assembling Code to Game is something completly different.

SPIM is a MIPS Simulator, and so it uses a different syntax. Are you that damn stupid to get that?

Btw, What kind of MIPS Simulator are you using? The name of the application please to be exact. Just saying, as you sometimes misinterpretate my arguments and come up with some shit, that doesn't haves anything to do with what I was waiting for.

It uses a different syntax, but not a completly wrong.

Mhhh, scratching my head... I believe there was a difference between a simulator and an emulator? Wasn't it?

With pleasure, read following:
http://www.inf.fu-berlin.de/lehre/SS00/19502-V/spimdoku.pdf

Look at page 13, you will find another example code, like the one I used here. He uses the same SPIM program like me. And so, I use the syntax that is given there. And maybe you actually read my replies: I've said, that I'm teaching in Lesson 1 generally the opcodes! Assembling them into game is something different, meaning, that I can't just use lw, but doing it the way like you described. And that's actually the lesson, which I'm currently writing on.

It's also a pleasure to me, that you call-ed me "sir". Why did you edited it out? You can't resist my attendance, can you?

if you'd look at page 18, you'd see, that the syntax is different. this site is giving 2 contradict informations, understanding the tutorial like you.
i think you didn't got the whole point of the LW syntax, how is it different from LI in your mind?

The codes in my tutorial work in SPIM perfectly. No errors, nothing. If I try the way, like it's supposed for SM64, it gives me an error.

Well, whatever. I delete that part of the tutorial and rewrite it, to make it more SM64-specific.

--------------------
Tarek701 is dead.
This really is seeming like a thread full of misinformation. If one were to read a tutorial here explaining MIPS assembly, they'd expect to be learning MIPS opcodes relevant to the Nintendo 64, rather than non-existent 'LI' commands and improperly used Load Words.
Updated the tutorial, most things are hopefully correct now.

much better, but still some mistakes/misleading informations;

this Stores $00030000 from T2 into memory location of T0+$2000.

this may be left from the old tutorial; sw doesn't change the value of any register.

(the sb command has the same mistake)

srsly, this starts to annoy me.
N64 Instructions-Opcodes List

This is a file that I have used a lot, it might be useful to have a list of all the instructions in one and be able to match an ASM instuction to an opcode and the other way around.

I haven't read the whole thing ( just the section titles ) but it looks like there is nothing about the FPU ( COP1 ), and I still found a mistake in your color coding at the end ( blue is an immediate value, not a destination register ).

The link above will also help for any particular instruction not in this tut ( like "JALR" and such ).

Thank you. I fixed some errors. Yes, some were from the old tutorial and I forgot to delete them. Now, I did.

The FPU and COP is a thing, that will soon come. The tutorial is not done yet. The thing is, I have to learn myself. I have to say however, that I learned a lot in that short time. Of course, I will extend the tutorial for FPU and COP. The thing is, we have to start with the basics first like simple loading/storing of values, branching and of course subroutines.

But thank you for that doc. I'm currently writing a MIPS r4300i patcher in C#, and I needed some good documentary about the instructions.

Btw, about that error;
It's actually not wrong. The syntax of BEQ says following:
"beq $s, $t, offset
Encoding:
0001 00ss ssst tttt iiii iiii iiii iiii"

$offset is in this case the destination. To avoid confusion I wrote $offset instead of rd into this.

EDIT:
If you're searching for the full N64ops, I have a even newer version, which is complete. It contains all N64ops docs:
