Adventures In Videoland (AKA Rollercoaster) from Creative Computing magazine, by David Lubar. For the Apple II computer.
First appeared in Creative Computing v8n1 (January 1982.) See https://archive.org/stream/creativecomputing-1982-01/Creative_Computing_v08_n01_1982_January#page/n61/mode/1up/
It was later republished in the book Big Computer Games (Creative Computing Press, 1984) See https://www.atariarchives.org/bigcomputergames/ or https://archive.org/stream/Big_Computer_Games#page/n109/mode/2up
ROLLERCOASTER-ORIGINAL is the code typed from the book. Tested but probably contains typos and defintiely contains a few bugs. This version can be used with an Omniscan videodisc interface by Aurora Systems along with a Pioneer VP-1000 laserdisc player, using the DiscoVision version of the Rollercoaster movie.
ROLLERCOASTER-2018 includes updates by Kevin Savetz. Modified to work with a Pioneer LD-V2200 or compatable laserdisc player. Fixed bugs, added a title screen, but true to the original.
ROLLERCOASTER-2018.sdl is the '2018' version, but with some serial port content changed so that it would work with the javascript Apple Basic interpreter.
ROLLERCOASTER-2018.vs is the '2018' version, but with the video switching opcodes added back in, in a form readable by Scott Lawrence's LlamaVideoSwitcher. (It sends on-screen display text to encapsulate the video switch commands)
ROLLERCOASTER-DVD. Modified to work with a Pioneer DVD-V8000 DVD player. Made a few small changes that pleased me.
