BASIS.SYSTEM for DOS 3.3 Launcher

Background

ProDOS 2.4 includes the Bitsy Bye program launcher. It can launch System (SYS), Binary (BIN) and BASIC (BAS) files. For other file types, if there's a BASIS.SYSTEM handler in the root volume, it is invoked to handle the file.

DOS 3.3 Launcher is a tool to run certain DOS 3.3 games (or more commonly, game cracks) under ProDOS. Launchers must be specially configured to invoke it for these DOS 3.3 files (file types $F1, $F2, $F3, $F4).

What's this?

This repro includes a BASIS.SYSTEM implementation that takes the passed file and invokes DOS3.3.LAUNCHER on it. It searches for DOS3.3.LAUNCHER starting in the directory containing the DOS 3.3 file, and then upwards. So you can create a disk like this:

  • PRODOS
  • BASIS.SYSTEM
  • DOS.GAMES/
    • DOS3.3.LAUNCHER
    • GAME1
    • GAME2
    • ...

And then Bitsy Bye will be able to launch them.
