Final Fantasy XII VM supports 100 known opcodes. There are three types of instructions. Instructions with an immediate, which are 3 bytes long, instructions without immediate, which are 1 byte long and special instructions like NOP and LABEL that have a defined size of zero and thus can't be used, because it causes the VM to loop indefinitely. These are probably used only by compiler and never put in the code itself.

|---|---|---|---|---|---|
| NOP | 0x00 | 0 | no | 0 | Don't use. It causes eternal loop |
