It depends whether or not you want to do it via converters.
Actually you can't do it via converters unless you're modding your TVC stick to work with PS2, then from there get converters for whatever system you need.
Alternatively, you can just mod it to work with whatever you want.
State what you want it to work with, and I can link guides/parts you need to get it done
For Xbox/PS3/PC
You can just do Xbox/PS3 since they're on the USB platform.
One of my peeves is that people say that its triple modded just because Xbox/PS3 work on PC
There are a few ways to do this,
Easiest for beginners is a PS360+
Works for what you need immediately and just requires you to be able to screw down terminals and switches automatically.
Thing is they're out of stock right now and won't be in stock for a while due to demand
Next is to use your choice of custom ps3 board and padhack a common ground xbox 360 pad to work with it
Needs soldering skills
