Hi German Krol. Welcome to the MARP! :o)(posted 9996 days ago)There's sure going to be a lot of us in the top 5 soon!!!
Since DOS MAME 0.31 you haven't needed to delete the .hi file - it is ignored if -record or -playback is used.
MAME will read your .cfg file for the driver you're using when you're making a recording, so if you've set the game to be easier than the default settings, it will record an easy game. It will also use those settings when the recording is played back. And then, Krool will watch your recording and tell me that you've used 'easy' settings and I'll have to delete it. I think that's how it works, isn't it?
