I have been watching this one. How far off are the Dev's from getting all the games to work with save state?
Thanks
There are 694 games with save state supported. (Info direct from 0.108u5 -lixtxml)
This is higher than the number of games supported in hiscore.dat (but hiscore.dat starts with a smaller group of games, so really this is really an apples to oranges comparison).
Adding savestate is a catch22. It helps in debugging, but possibly a moving target if emulation isn't finished, and not needed for debugging if the emulation is perfect.
This is why mameDev is suggesting the users to help add savestate to games already emulated; they'll worry about the moving targets where they need it for debugging, the people who want to help a little and learn about mame can add to the games they like where they need it for playing.
