Can someone tell me some good combos? Thanks
Note the title and what I have bolded in it for you: Ryu General Discussion: Frame Data, Strategy, Combo, etc.
General combos are there on first page. If you are looking for more specific stuff, just post in that thread, what you are looking for.
I assume the combos still work for USF4?
Yes. Ryu’s move properties are relatively untouched throughout the Street Fighter 4 updates. Those combos are all still viable and useful.
