Just had a first try at
Pitfall II - Lost Caverns for PCjr. I jumped down the big ladder, so I could autostich the video (only vertical scrolling, horizontally it's screen swapping). The invincibility cheat I made with Cheat Engine was helpful, otherwise I would have been taken back to the checkpoint (red cross) several times. It will also be helpful for the annoying way up on the other side (if you don't know what I'm talking of: count yourself lucky). In addition, the cheat allows to climb at any line parallel to the ladders.
I'm meditating on if I should include the enemies. If I do it, I will probably take the first position they are fully visible, which means a lot of short video takes and using Autostitcher frame per frame...
It will be a map with notable horizontal and vertical spread but without blank spaces - wonderful!
