The following was added/fixed:

I fixed the AY-3-8910 emulation (missing noise channel and I/O ports), fixing the sound in all MSX games and many Arcade games using this chip.

For example, the sound in 1942 is now perfect.

Fixed the gunsmoke arcade driver.

I also solved a problem in the MSX VDP emulation, which fixed the colors during boot-up sequences of the Konami games.

I added support for online high scores in 6 MSX games (The Nemesis series, Salamander, Parodius and Penguin Adventure).

Last but not least, I started adding support for MSX2, but I´ve got a long way to go until I can show something complete.

I´m starting with rudimentary support for just SCREEN 5 because that is what most games use.
