This Sega Master System / Game Gear emulator has been updated with the following from the homepage:

"Here is a new, and probably the last release of Osmose. I spent a lot of my free time working on this emulator and now it's time for me to switch to something else. I will not work anymore on the emu, except for bug fix.

What's new in Osmose 0-8-1:
