    Hmm, fail. That's send ax, ax. I meant 0x5000.

    So yeah, my bad. But hey, there's a solution! Encode the opcode directly! "dw 0x5090"

    Well yeah, but the assembler doesn't expect you to actually try doing so.

    I could've sworn I read something like "Any instruction is capable of encoding a single immediate value and not more than that, which means that instructions such as mov [0xCAFE], 0xBABE are not possible to encode [unless the address and value to be written are the same, which is unlikely]"

    I'd look into it but I'm totally out of context. I hate to say this but you should just try to avoid passing two immediates.

    Well, maybe it's just not designed like that

    I know you can only pass one immediate value, but you should be able to use it multiple times in a single instruction.

    Yes, it is not possible to pass more than one immediate value, sadly. Did you read instruction reference?

    Not all we need is negatives. :) Nice work, I can do simple games, but nothing like this. Happy to see that it can be done (I say this in almost every computer save I see) +x^2+2x+1
