Does anyone know of any game libraries for TP 7.0 that I can legally use both commercially and non-commercially?

Recently I got itch to make game for DOS, using Turbo Pascal 7.0. But default libs that come with the compiler are of no use for that purpose, what I'm gonna do? Use Graph unit limited to 16 colors and do sound on the bleeper? I'd like something that can at least support 256 colors and sb. Anyone knows of some TP 7.0 game-oriented libs doing that?
