Very cool read over-all. Finding a bug in a game that is over four decades old is hilarious.
> What was amazing though is that all throughout all the code that handles scrolling and clipping, vertical parameters are supported.
Possibly the vertical parameters were either 1) part of the "library" the author had created but not needed for Choplifter, 2) to allow for offsetting the world on other (6502-based) platforms or 3) maybe intended for "bumping" the display when the chopper crashed?
Sounds both tedious and fun (the way solving a logic puzzle is "fun").
(A little surprised to find that Quinn does more than just work on steam engines as I have watched her YouTube channel for some time now — watching her building on her metal lathe and mill.)

Same! Her Youtube channel is the best resource I know for the hobbyist machinist. What a breadth of knowledge. I don't know how old she is, but would guess she probably wasn't even born when this game came out, so I'm astounded to learn she has decades of experience with Apple II dev.

Tangent, but curious if anyone knows why I'm seeing a handful of ' ' / U+FFFC OBJECT REPLACEMENT CHARACTERs peppered throughout the post on Linux FF? From their position at the end of sentences I figured they were emojis my system is missing, but I pulled it up on my phone and there's nothing there - or more accurately, it seems iOS Webkit just renders U+FFFC as a blank space. Emojis that got garbled by her CMS perhaps?
I wasn't aware she did steam engines - I knew about her from her "Veronica 6502" computer, which she designed and built. And lots of other computer hacks. She's certainly versatile.
