5 years ago I did use an ale.cfg to set this parameter to 0 and implemented frameskip myself. This was to allow for deterministic behavior based on the random seed.

In the Atari experiment there's a probablistic action repeat (frame skip?):
My reading of this is that the behaviour (or something very similar) is enabled by default in ALE (since 0.5):
When you call self.ale.act(a) for some action a, the action a will be executed right away with a probability (1 - p), otherwise, the action that was previously executed will be executed again. The default value for p right now is 0.25.

I assume it's safe to remove this test from the code (unless there's an ale.cfg in place to disable the default ALE behaviour).
Apologies in advance if I've mised the point :-/ ...still learning.
