Digital YM2413 FM sound emulation.
Drums sound real good, too.
Made some internal changes and clean-ups to the source code. Fixed some centering problems with screen expansion on GG games. Everything has been rewritten from scratch. The emulation is much more accurate, as a result compatability has improved greatly. The DOS port has a lot of nice features added, including 16-bit color, display blurring, digital sound emulation, and scanlines, which were the most requested items.
