I was going to use a 4-frame running animation. I just haven't had time to do it. I have little time to do this and when I do I often have a baby in one arm and the other for NESmaker. And I am also trying to do my daily Sunsoft research I used a 4-frame run animation for my Unity version but I had just settled for a 2-frame that looked decent for now.
Here is a video of the Unity project https://youtu.be/fk8yZi2P0Wk
Here you see the artwork of Bionic Girl and hear the theme song (that is being remade in Famitracker soon).
There is more game in the NESmaker version than it ever was.
I'll take a look at it this evening.
Thanks for reminding me of that. I read about it and forgot. Making a note.
