KansasFest 2020, July 24, 2020, 1:45 pm - Out Of This World: How It Was Done - Rebecca Heinemann
KansasFest for 2020, the 32nd annual Apple II convention, was held online July 24 - 25.
A deep dive into the technical challenges in porting the Amiga version of Out of This World to the Apple IIGS, to prove that the 65816 was powerful enough to run the game, paving the way for a Super NES version. Issues covered include how to trick players into thinking the frame rate was higher that it really was; high speed polygon fill functions without using Fill Mode; and two-key rollover by directly reading the ADB stream from the keyboard for better game play response.
KansasFest is an annual convention offering Apple II users and retrocomputing enthusiasts the opportunity to engage in beginner and technical sessions, programming contests, exhibition halls, and camaraderie. KansasFest was originally hosted by Resource Central and has been brought to you by the KFest committee since 1995. Any and all Apple II users, fans, and friends are invited to attend.
