hi there,
there seems to be some dfferences between opcode generated by rta and that generated by softice and hiew.

dunno...neone else had some problem like this ??

yup there are some errors
eg: mov eax,eax=89c0
RTA: mov eax,eax=8bc0

SQUIDE! would like comments and feedbacks

There's more than one way to assemble an instruction, so instructions assembled by different programs may differ in the binary they produce.

However, you can be sure that they disassemble back into the exact same instructions, and execute the same. Eg. 89c0 and 8bc0 are identical in the command they perform.

To check, I've just created a small EXE in MASM, and db'd the hex bytes directly into the program. Disassembled by OllyDbg, W32dasm and IDA all produce two lines of the same instruction.

From the masm32 opcodes help file:

The MOV instruction.




looks like an operand size difference. However, in the case of mov eax,eax - such a thing would not matter, if you think about it. So in that case they are the same.

When it comes to opcode programmers with hexeditor its a pain on ass

Maybe, but complaints to Intel please as my prog aint faulty

DOH!

squidge:

Allow me to correct you, that should read "my program isn't faulty."

Regards.

Well, hello Mr. Pedantic

Well that certainly raises the level of discourse. And that aint bad.

Regards.

Be Pedantic,DOH identic
Its not a complain its feedback,check that or get whacked

Regards
