It's interesting the differences you've made Sasha. Now if I can add some features to get the authentic looking consoles in there you could make some more interesting videos with those variants! The new 3D sound engine has a lot more flexibility in regards to how sounds come out too with stereo systems for instance.


Thanks :)

Yes there are some fixes to the Z80 in regards to NMI and RESET behaviour. Not sure how many games it may affect but there are a couple that I think didn't work due to some Z80 interaction issues previously.

I can't remember the exact amount of Genesis games Sasha found that had issues but it certainly wasn't that large a list and I will go over it at some stage in the future to try and get 100% compatibility with Megadrive.

I spent some time today working on the Megadrive core and tested most of the games listed here as not working. They are now working. :)
