Hey all - I'm a speedrunning fan but not a runner.

Supposing I did want to get out an old DOS title to run through Dosbox and try some runs, is it generally frowned upon to use anything other than the standard keyboard controls?

Basically I've been playing with a custom profiled DS4 controller. Nothing fancy going on - just directions and a shoot button, with my livesplit hotkeys mapped onto the controller also for convenience.
