DC converter to PS2?

I know this has been asked but I wasn’t able to find anything solid about it. I’m thinking about buying an Agetec Stick for my Dreamcast but my friend has a PS2 so is there a converter for that? if not, would it be a better idea to buy a PS2 stick and get a converter for DC?

Thanks a lot
