Oh, it's definitely decodable. Most CPU's can be (though x86 post-386 wouldn't be fun), since that's what they're usually doing internally. But, with 8-bit CPU's, the opcode space is usually limited to a byte, which makes tables very doable and very efficient. My rust-based GB emulator uses a decoder based on those very docs, in fact. Though, modified slightly since the GB's CPU only supports the CB-extended range operations. |
