Maybe I will test with some more to get a better picture of where I am at. But, Gameboy emulation is certainly good enough to release. Maybe I will have a crack at the sound first, though. Here's some screenshots of a previously unemulated game called Clash Road . I also added sprites and palletes.
Some games try to run but stall during their intros.
Also, the alta vista links are now at the bottom of this page. The only problem is that I haven't done sprites yet. But that looks easy enough. There is still a graphics glitch that I need to iron out, as you can see in the Duck Tales 2 screen shot. I may restart this from scratch rather than try to massage to current code into the new design.
