How do I make a mod require another mod?

[STH The Mobian Resurgance]

I want my mod to have the Adventure Sonic moveset and colors, but, I want to make it to where you have to download Adventure Sonic and support MetalWario64's mod, rather than just steal his mod and add my own sprites and call it a day and leave. I doubt that MetalWario64 would let me basically re-upload Adventure Sonic but with different sprites, as less people would go to his mod if they somehow like my sprites better (I highly doubt that anyone would lol)
