| Version 1.0 | 6/23/08 |
|---|
| Getting started. It took over 3 weeks to do this, but only 3 days of that was spent on dis/assembly. Most of the time put in was learning and implimenting the goddamn API stuff.
|
| Features |
|---|
You might recall the half-assed disassembler I wrote in VB6 before (part of Renegade). This one is all C and Win32 API. Hopefully, it's the last one I feel the need to write for MIPS.
Current Features:
- Dis/assemble 3 MIPs languages
- ASM Searcher
- Header view (PS2 ELFs and N64 ROMs)
- Valid XHTML 1.1 readme. ;-)
Possible To-Do List:
Known Issues:

| General Notes |
|---|
My disassembler is sort of a Win32 style Niew. You'll notice you can edit hex/asm and the opposite changes accordingly. A couple of notes...
- ALL values entered are expected to be Hexadecimal.
- I tried to make this as true to each language as I could, but good documentation is hard to come by sometimes.
- Edit ASM/hex/address(go to) by doubleclicking or using a shortcut key (see below).

| Keyboard Shortcuts |
|---|
| Key(s) | Function |
| F5/CTRL+G | Go To (You can also doubleclick any address box) |
| F3 | Edit hex. Press again to move over to ASM. Shades of Niew. :) |
| Immediates/Jump Targets |
|---|
Jumps and other opcodes where you use a value are fairly forgiving on syntax of the value.
Some Examples:
JAL 00000060
J 60
JAL $60
J 0x60
BEQ $V0,$A1,0x00000068
BNE $V1,$S1,68
ADDIU $V0,$V0,00FF
ADDIU $V0,$V0,FF
ADDIU $V0,$V0,$00FF
ADDIU $V0,$V0,$FF
ADDIU $V0,$V0,0x00FF
|
| Registers |
|---|
Registers are another thing I tried to make flexible.
Some Examples:
ADDIU $V0,$zero,00FF
ADDIU $V0,zero,00FF
ADDIU $V0,R0,00FF
ADDIU $v0,R0,00FF
ADDIU V0,R0,00FF
ADDIU R3,R0,00FF
ADDIU 3,R0,00FF
LUI $K1,3F80
MTC1 K1,F2

| ASM Search Info |
|---|
If you ever used Renegade, you might remember it having some useful (and probably buggy) R4300i search options. This is basically an expansion on that type of searching.
- ALL values input are assumed hex!
Search Types:
- References to a 32-Bit Value - Looks for LUI $*,XXXX and another op with the lower half of the address.
- LI 16-Bit Value - Finds ADDI/ADDIU/DADDI/DADDIU/ORI ops which load an immediate to a reg ($reg,$zero,value).
- SLTI/SLTIU 16-Bit Value - Finds SLTI/U ops whose entered value matches the entered one.
- ADD/OR 16-Bit Value - Finds ADDI/ADDIU/DADDI/DADDIU/ORI ops which add/or an immediate to any reg ($reg,$reg,value).
- AND 16-Bit Value - Finds ANDI ops whith an immediate matching the entered one ($reg,$reg,value).
- J/JAL Address - Pretty self-explanatory.
- 32-Bit Value - Your basic Known Value search.
- 32-Bit Value AND Mask - Known Value search, with a twist. The file is searched for values that (value AND mask) == entered value.
