Basically, you're stuck for now. Since it's never been officially stopped, we can't say that development has discontinued on Chankast. However, if you look at the last time any part of it recieved an update, you can get a rough idea of when you might see the next release. Basically, if there's a release within the next 2 years, that's pretty good. So, use the memory card saves every chance you get. Besides, with how buggy this emulator is, relying on savestates would probably crash your game faster than just playing straight through. Mouser X over and out.
