ares v123 includes significant improvements to the emulation of the ColecoVision, SG-1000 and the Game Boy/Game Boy Color.

This release brings the compatibility rating for ColecoVision and SG-1000 to four stars.

This means that we have 100% compatiiblity with both of those libraries, with the only exception being the few games that require additional peripherals (driving controllers; touchpads, etc).

The Game Boy improvements are significant, but not quite enough to increase the compatibility rating at the present time, even so, Many more games are playable than before.

Finally, a few tweaks to MegaDrive emulation have improved compatibility, reduced the occurance of video corruption, and improved performance of the Sega 32X emulation.
