If you don't see it, take a look at the platform in the upper-left.
I did finally get Super Mario Land 2 to work right. I've never been able to get it past the title screen, even in the old emulator.
I'll put out the first real release after I fix the remaining (hopefully few) bugs and create a dialog to switch keys.
Also I've decided to make the project open source, but it'll be after I'm sure this thing is 100% correct. Not sure what license I'll use, but it sure as hell won't have "GPL" in it.
Edit: Fixed the bug in Mega Man V.
