Thank you for the huge compliment! :)

QBASIC was based on QuickBASIC but was actually on DOS, that was on my old 386 PC before I switched to Mac.

Agree on a lot of today’s software. Hard to satisfy dependencies on some web based code even after 3-5 years depending on framework and tooling.

The emulator was written in plain C++ using the standard template library and the SDL graphics library, which is still being maintained. Which all explains why it still compiles and runs cleanly. Even though I wrote it on Mac it’s easily portable to Linux or Windows.
