How do you do it in Axe outside of a million Pt-Mask() commands?

You could write a custom bitmap routine, I guess.
I'm several versions behind on Axe, I haven't even seen Pt-Mask. Advance Wars uses its own masked sprite routine.

What was your solution to that, Sir? Could you input arbitrary numbers for the size of said bitmap?

Well, you can define them at compile time, and you can use SMC to define them at runtime.

Hmm...
How would one make his own masking routine?
What are the basics of masking?

Well, I made one sprite completely black (sprite A), and the other one was just the white pixels (sprite B), then I used Pt-On first with sprite A, then Pt-Change with sprite B on top.

No. I'm having trouble sending things between my calc and my computer. Just try it on your own, it will work.

This is actually how masking is done in xLib too (though most people prefer using AND/OR masking, but AND is not an option in Axe)

I used XOR to do sprite masking in my axe game. I would draw on one sprite that contained black for everywhere that I wanted to be masked using OR logic (Pt-On), and I would draw a sprite over that with black for all the areas of the masked sprite I wanted white using XOR logic (Pt-Change).
EDIT: oh wait, SirCmpwn already said that

Quigibo? Any ideas? Maybe add in this badass feature (masked bitmaps)?

I would like this feature. I think it uses TI's routine, though, so I am unsure how it can be modified.

The Pt-Mask() is a way to automate exactly what SirCmpwn was talking about. There isn't a way to optimize it further outside of writing an Asm routine.

Is there ANY WAY to mask huge sprites without the Pt-Mask()?

You can write a gazillion pxl-change()/pxl-on()/pxl-off() but that's really slow. Like I said, your only other option is inline assembly or multiple Pt-Mask() routines.
