Yeah because we can really read minds.
0x90 is a NOP... and?

I think he's trying to figure out the bytes for all the opcodes.
It's a lot of work, trust me.
Open up assemblerunit.pas from Cheat Engine, or my opcode.dll.

Look for a file called OPCODES.HLP on the internet available for download. I think it's also packaged with masm.
| Code: | Bare Hex Opcodes And Mnemonics
This list include opcodes that are not in the main listing.
NOTE : There are redundancies in the Intel instruction set which show in this list as duplication of both hex opcodes and mnemonics.
More detailed reference can be found in the Intel Architecture Software Developer’s Manual Volume 2 : Instruction Set Reference found in the file "24319101.PDF" from Intel.

I haven't really gotten around to putting opcodes in my engine, so I haven't looked over it for long. The best way to be sure is to load up any random game and attach to it with CE, then go to Memory View and search that opcode.
EDIT: I just checked, and yes, 0x75 is JNE.
