Is DOSBox allowed for running or do I have to use the joeQuake sourceport since I'm not natively running dos?

I made a few aliases for casual play so when I press middle mouse button down, it does +jump and +forward, then when I release mmb it does -jump and -forward. Here is the bind and aliases: alias +bj "+jump; +forward" alias -bj "-jump; -forward" bind mouse3 +bj
