Here’s what he has to say about it:
“This is a TI-82 remake of the Commodore 64 soundtrack for the game Warhawk, originally composed by Rob Hubbard in 1986. It is programmed down to the deepest details on a Texas Instruments TI-82 graphing calculator (from 1993) using the tracker software HoustonTracker 2.
The video starts with a tech dive into how sound is generated on Commodore 64 and the TI calculator, as well as 1-bit audio in general. Then the song appears, including a custom-written visualizer to make the insides of the tracker come to life.”
HousetonTracker is a music editor/sequencer for the Texas Instruments TI-82, TI-83/82STATS, and TI-83+/84+/SE. It lets you compose and play multi-channel 1-bit music directly on your TI graphic calculator. HoustonTracker 2 is available as a free (donationware) download.
