So, I've been using CE for a while now, enough to know my way around to use it.

I've been using IDA previously as it's really my main go to debugger because it's just way more powerful.

But, I was using CE to grab some opcodes out of a trainer I was writting and wanted the opcodes not the mnemonics, but it gave me the mnemonics.

I think your definition of opcodes is wrong. When I checked the opcode box, it doesn't give me the list of opcodes, it gives me the mnemonics.

Opcodes are the binary encoding of the assembly functions for the processor to read and based on those the processor set the gates accordingly.

For example.

OPCODE: 90
MNEOMNIC: XCHG EAX, EAX

It's just confusing to an experienced reverse engineer, I guess to someone learning it might make sense, but it's just plain wrong.

Just a little nuisance when debugging with CE, as I keep clicking the opcode box and getting mnemonics instead.

I thought it is like this:
Byte code: 90
Operation code: XCHG EAX, EAX (aka NOP)

Therefore,
Operation code = OpCode = Mnemonic = Instruction

What would the option "bytes" be in the choice : address, bytes, opcode ?

Anyhow, if you feel like it you could make an en_EN folder in the languages subfolder, copy the .po files to there and add translations where it says opcode and change it to mnemonic
