Multiline Ultimate Assembler 2.3 (1) by RaMMicHaeL
Multiline Ultimate Assembler (formerly MUltimate Assembler) is a multiline (and ultimate) assembler (and disassembler) plugin for OllyDbg. It's a perfect tool for modifying and extending a compiled executable functionality, writing code caves, etc.
General:
- MUltimate Assembler is a multiline (and ultimate) assembler (and disassembler)
- To disassemble code, select it, and choose "MUltimate Assembler" from the right click menu
- To assemble code, click the Assemble button in the assembler window
Rules:
- You must define the address your code should be assembled on, like this: <00401000>- You can use any asm commands that OllyDbg can assemble
- You can use RVA (relative virtual) addressess with a module name, like this: $module.1000 or $"module".1000, or $$1000 to use the module of the address definition (e.g. <$m.1000>PUSH $$3 is the same as <$m.1000>PUSH $m.3)
- You can use labels, that must begin with a '@', and contain only letters, numbers, and _
- You can use anonymous labels, which are defined as '@@' and are referenced to as @b (or @r) for the preceding label and @f for the following label
- You can use C-style strings for text and binary data (use the L prefix for unicode)
Example:
<00401000> NOP ; This is a nop
JMP SHORT @f
@str:
"Hello World!\0"
; L"Hello World!\0" ; for unicode
@@:
PUSH @str
CALL @print_str
RET
<00401030>@print_str:
RET 4 ; TODO: Write the function
