[Version 0.9]
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.
Also new is a Sony Playstation port, though it's highly experimental
and has some serious performance issues.
SMS Plus is now free software; the source code is available for anyone
to use as they see fit, and is distributed under the terms of the GNU
General Public License.
